Sony's saying Vita support will match PS3 support going forward. They mention that one big mistake they made with the PSP was shifting resources away from it after a couple of years, which hurt it in the long run.

"Speaking before E3, Sony's head of WorldWide Studios Suhei Yoshida told us that the company's decision to concentrate much more on PS3 software than PSP titles was a "mistake" and hurt the handheld."
"We are doing about the same number of titles [on Vita as on PS3] so that means a lot," he stated. "One of the things we didn't do to well to support PSP was that right after PSP came out we moved on to working on the PS3 launch titles."
"We tried to back it up a couple of years ago but there was a time where we were not offering enough PSP content. So going forward we do not want to make the same mistake so we always look at the balance that we are doing in support of both PS3 and NGP."
