Does the wi-fi version come with any memory cards? will PS Vita be able to play PSP games (downloaded, ofc i guess) at all? I need to play Persona games. I spent my money on Vita itself and I need to debate whether on getting a game or a memory card right now. I forgot to ask this, how would I stream Vita through a PS3 to stream it on TV? Do I need osme kind of a cable or something to do this? I already have a PS3.
