So, let's just do a little survey of the field:
- Retail support is at an all-time low in the west. The Vita gets a very small and shrinking amount of space at a small and shrinking number of retailers.
- You need economies of scale to reduce production costs, and the Vita doesn't really have any. Existing costs reductions have occurred by using cheaper components at the expense of product quality.
- Sony has not given significant first-party support in several years. They have released a few titles, but nothing big, and nothing that's a focus.
- Sony has not given the Vita any real attention at media events.
- When Sony does promote the Vita, it's as an indie download machine, as a controller, or as something that can take advantage of remote play.
- Publishers are not generally interested in releasing retail software for either handheld, instead favouring mobile or consoles. As an example of this, Square Enix decides to port a moderately high profile PSP game... and releases it for home consoles and not Vita. Simultaneously, they are making millions of dollars off their very successful mobile ventures.
- Every significant publisher has made it clear that they want to reduce risk by focusing on core opportunities and releasing fewer SKUs.
- No third party publisher save small Japanese firms are releasing software on Vita, and those projects that are announced are generally low-impact projects.
- Sony is closing up PSM, admitting that their plan to encourage cross-platform mobile and Vita development has not taken off and is not worth spending resources on.
- Tearaway, which is probably Sony's last core high profile Vita release, is getting a console port. Gravity Rush has been rated for consoles (perhaps an error, or perhaps an indication of a port).
- Playstation TV, which could have been a productive way of cost-controlling, is generally regarded to be a weak product that has not received market traction anywhere in the world.
- Also, I'd add that third party companies don't pump resources into making hardware a success, they pump resources into successful third-party hardware to capitalize on the success. If Square Enix and Take 2 released the slate of software you're proposing on the Wii U, they'd probably drive sales, but they wouldn't do so because it makes no sense to focus on the Titanic to try to get it to miss the iceberg.
None of this is a comment on the quality of the Vita, which by all accounts seems like a great little handheld, with lots of great indie games, some interesting original content, and what's obviously a very high user satisfaction rate. But I think it takes some pretty bonkers logic to look at the state of the field, and say "well Falcom announced a new game and I don't feel like New 3DS is a big deal... so what if every publisher suddenly started releasing all their big guns and porting their biggest titles and focusing on the Vita even though they didn't do any of this for the last 5 years... couldn't the Vita become big again?" Like, I just don't see how a measured reading of what's going on in the world could lead to the conclusion that the Vita is about to turn a corner.
I'm not saying there won't be games being announced for Vita. I'm just saying that it makes more sense to enjoy the library the platform gets rather than projecting dreams of world domination.
