Holy shit I hope this is real.
Realistically, I don't think it would be a complete collection, even if called Complete Chronicles. The N64 and PS2 titles I don't think they'd figure it was worth it to make ports, or more likely emulators, for the vita to play these games.
Then again, if they really wanted to put forth an initiative to develop emulators for future project collections and such, it is possible. I just don't see it as very likely.
I'd expect NES, SNES, Rondo, SotN, Chronciles, and maybe DXC in one bundle. It could be as cheap as DXC + Chronicles being the only Chronicles titles.
