definitely!
I'm pretty sure they had to announce every single third party game even remotely coming to the Vita, tonight, in this Sony presentation.
A lot of people have such a sense of urgency about Vita that they think Sony had to really do that, expose the whole barrel.
Now maybe they're right, but I don't know if SCEJ quite shared that sentiment. And even if they wanted to they couldn't do that. A lot of pubs simply would not want to debut games at a webcast alongside others like that.
