My main issue with the Vita being a success is this: the 3DS' second lowest week ever was two weeks before its pricecut in Japan, at 15,819 units according to Famitsu. The Vita has outsold that mark 11 times out of the 63 weeks that it has been around. It's not that the Vita's not living up to standards of the 3DS, it's that it's been completely outclassed by not only the 3DS, but by the Dreamcast, which also had a much higher software tie ratio than the Vita (its biggest selling title is less than 250,000 units in Japan). To put this in perspective, the Wonderswan, a niche console that the Vita is tracking closer to than the Dreamcast at this point in its life, had its biggest title (a Final Fantasy I port) at 376,367 units. The Gamecube had a million seller. The Dreamcast had something around 400,000. If Sony wanted/wants to save the Vita, they'll put out Gran Turismo, but it's going to be buried underneath the launch of the PS4/Durango (in America/Europe), the Wii U's holiday lineup, and the 3DS lineup.
And all of this proves that you aren't paying attention to the post you replied to. At all.
The 250K number you have is tied entirely to retail sales for Japan alone. Since Sony doesn't release digital distro numbers you have no idea what it's actually doing on software.
So now you are not only trying to move the goal posts to the software side of sales but also trying to base conclusions off of fragmented data.
Again, retail software numbers are not nearly as relevant for the Vita as they have been for previous hardware. Digital distro is a significant game changer for the device.
The only thing they lose to weak retail sales is the support of major 3rd parties, which they don't have and can't get anyway as the 3DS is a far larger market.
I like the Vita. It's a good console, and I'm happy that its getting tons of indie support recently. But that doesn't change the fact that FFX HD isn't going to do anything of major significance when you can play the same title on the PS3, and Squeenix has been extremely slow at trying to get the title out. I hope Sony does put Gran Turismo along with a price cut to at least try to spur sales, but I have serious doubts about the future of the console.
Why?
You haven't made a real compelling argument as to why the Vita is so amazingly doomed, just trotted out spurious correlations to previous hardware. Sony isn't Sega or Namco Bandai, they have a long history of supporting their hardware long term and re-positioning it as needed to find new avenues for profit (PS3 is one recent video game example, but Betamax is probably the company's best example overall).
The Vita was clearly built with a Nintendo style business model in mind in the event that it did not have a strong initial outing in the market. The hardware does not produce loss, the peripherals make nice profit, the first party heavy lineup and distribution channel is giving Sony greater per unit profits on software sales, and the format is conducive to smaller developers looking for a niche. Nintendo typically gets the smaller traditional 3rd party pubs and partnerships with 2nd party studios, whereas Sony is instead now targeting indie studios.
This model is safe and it works in this industry if you know your target customer. Nintendo is not employing it with the 3DS because they became what Sony was with the PS2 - the massive vessel upon which all the major 3rd parties are riding. That is why when 3DS sales stumbled out of the gate Nintendo chose to incur hardware losses like they've never done before. They had to meet expectations of their 3rd party partners. Vita has not done that because Sony's price point isn't going to sway major 3rd parties to their side and would instead truly hinder the device's long term outlook.
Also, indie/second tier titles actually are highly relevant and out of nowhere games are setting monthly profit records all the time. Puzzle & Dragons has
daily sales of $2M USD a day. It's a nine figure annual sales monster that eclipses anything else in Japan's gaming market and it came from an out of nowhere publisher (who have already released a unique Vita title by the way).
As long as titles like Puzzle & Dragons, Angry Birds, MineCraft, etc. can dominate handheld devices via F2P models and competitive pricing we'll either see the dedicated handheld market react or contract. Right now it's doing a whole lot of the later. Sony is only just now starting to position the Vita to take advantage of this groundswell, while Nintendo has done very little at all.
The business model for Vita has been proven in this industry before. Assuming Sony is unable to maintain it when they are doing so currently and have done so before is extreme pessimism. If they are unable to maintain any of this momentum (or the momentum gained from Soul Sacrifice) or if they lame duck the trade shows then the skies will start to darken, but as it stands now Sony has a lot of moves left to make with the Vita before shutting it down/relegating it to a PS4 peripheral.
