This is most certainly true! It will all be moved to Tv/mobile after the Vita.

Doesn't this occur at the end of each generation/beginning of a new (for every console)???...and the ps3 userbase will be nowhere near the size of the ps2's (was last gen)

No, PS consoles have always had a high attach rate that's all that will matter to 3rd party devs.

The failure of the PS-Vita, along with the PSP and PS3 not being market leading consoles, will have some impact on how third party publishers approach the PS4 but it won't kill off support for the platform ...

Essentially, with the PS3 most third party publishers allocated most of their best teams to producing PS3 games (for most of their biggest franchises) before the PS3 launched. With the PS4 I would expect publishers to be a lot more platform agnostic and wait for sales before they throw strong support behind any one console.

I think everybody knows psp was the worst playstation system. Sony handhelds have never done as well as nintendo. I still think third parties will throw support at sony but I disagree with a lot in this thread. People are becoming wary of sony systems after ps3 and vita's slow start. So yes it will have a negative impact on them.

This shit... this is the problem. People think this is actually true.

It was true for the 3DS, and that had a fair library in its launch window compared to Vita's.

That Apple example was very uh...Apples and Oranges.

People were still buying the 3DS at $250 more than they are the Vita despite the Vita having the superior first year library. A lot of it comes down to price, silly forced proprietary memory, but also brand power. The Playstation brand has been greatly diminished over the last 6 years and has been climbing uphill ever since the PS3.

PSP sold more than 70M units. The second best result for a non-Nintendo handheld was Game Gear with 8M. So it's a very good result. 

If anything, this'll only mean that PS4 will get fewer 3rd party exclusives. But that's probably true for the entire industry; games costs too much to make these days that devs want to sell as many copies as possible, and therefore selling on more consoles.

Western developers probably won't care about the failing Vita, whereas Japanese dittos might.
