The 360 did close to 200k this holiday using your numbers. Including the rest of the year assuming it sold 25-60k range od say it was close to 500k the whole year.
A $99 price for the non-gimped 360 or less, for most of the year, along with the deals for Nov and Dec, I can see 1 million.
Ps3 I could see 500k, though the reduced retail presense may cause that to be harder to reach, I forgot some stores dropped the ps3.
I hear what you're saying. $99 means around $85 wholesale assuming a slim retail margin. Gets you to mfg cost of goods number around, I dunno, let's call it $50 (maybe more, maybe less), at a slim mfg margin (definitely not $50/unit). Can that box be built for $50? Not sure.
On top of that, the first party would have to price protect the existing channel stock. So, every retailer would get some $ amount per unit for every Xbox 360 and PS3 they have in stock. A pretty pricey *ba dum dum* proposition.
Finally, you have the element of price anchoring to consider. Basically, by keeping the old box at a relatively high retail price, it has the effect of making the new boxes seem cheaper. Right now, you can get the Forza Horizon 2 500GB bundle at Best Buy for $199.99. You can also get the GoW Xbox One bundle for $349.99.
So, the consumer could look at this and say... "For $200 I can get the old box. But oh wow, for only $150 more I can buy the brand new box instead of the old one? That's not a bad upgrade price".
Now if that Xbox 360 was $99.99? "Oh man, that Xbox One bundle is $250 more? Forget that, I'll stick with the $100 version".
One of the potential causes of the very strong next gen adoption rate is that the old consoles were priced higher at this point than in previous generations.
Just saying, these guys likely have strong strategic or budgetary reasons for not going $99.99.
Your argument makes sense but I don't think the target market for Xbox 360 right now is made by people that will pay $150 more for have a Xbox One.
I think you're missing the point a little bit. All the digital revenues, the DLC, and the new game royalties are all on Xbox One. One new Xbox One owner is worth more over the next 5 years than a multiple of Xbox 360 owners, who will likely buy software used or at low cost new, won't buy a lot of digital DLC or games, etc. If by price anchoring you get a fraction of potential Xbox 360 buyers to the Xbox One, you're making more money over the coming years.
Look at Sony, which is basically leaving PS3 on the vine. No real bundles, no promotion... if people want to buy one, well that's fine, but they're certainly not pushing PS3.
In my mind, neither mfg is pushing old gen development or promotion in any meaningful way. They want people to adopt the new stuff, and if that comes at the expense of some sales of the old stuff, fine.
