Gungho wants the 3DS version of Puzzle & Dragons to sell a million copies so there would obviously never be a Vita version.
Like having a Vita version would damage that. So I suppose having an Xbox360 version of Call of Duty damages The PS3's sales? Or that Batman Origins Vita will hurt Batman Origins 3DS?
This is an awful idea. Porting PSP games to PS2/PS3 only hurt PSP as it gave less of a reason to buy a PSP. The same applies here except magnified 100x worse due to Sony using Remote Play as a replacement for native Vita software, meaning if PS4 ports became a trend there would be little reason for even Vita owners to buy the original release.
I covered the first part; it doesn't have to be exactly the same game, they can just make a later game in the series, if they want. Or make things similar to the Killzone and GTA games of PSP; thinks that can use much of the same assets, yet tie into the mythos well. Basically, game that are similar to the Dead Rising Case West / Case Zero / Dead Rising 2 situation.
The point is the Vita doesn't have many console-retail-quality games NOW, and development is focused on more expensive PS4 games. Why not use mid-level development assets to make a Vita version in 2013, and then upgrade the assets for release of improved, "new content! New graphics!" Versions in late 2014/15, and beyond?
Heck, since you already have the Vita-level resources ready, why not release a cross-buy release of the upgrade (or make the upgrade Vita DLC that comes with the purchase of the PS4 version), like Playstation All Stars did, and increase the value of the new product that way?
Remote Play is an important option, but so is Cross-Buy, Cross-Play, Cross-Save, etc. Sony can use any off those to increase value of a release, or to get Vita owners to want to buy a PS4, PS4 owners to want to buy a Vita, PS3 owners to want a Vita, or Vita Owners to want a PS3.
Imagine if "Exclusive PS4 content" between it and Xbox One became 2+Hour Exclusive Vita-playable games? Or how about making a buy of the Vita version, lead to a 10 dollar discount of the later PS4 Digital Version, similar to a PS+ user discount?
I really think the biggest enemy of the Vita, ATM, is that it's basically equal to developing for an HD system. If any company is going to make a game that expensive, why not make it on install bases that are bigger, and promise more ROI? 3DS (and PSP) don't have this issue, as you can make cheaper-to-develop games, and for a much larger audience.
But, if you think this idea is bad, what would you do to get retail-quality exclusives, timed or otherwise, onto the Vita?
