I hope Sony doesn't pull this shit when they get PS3/PSP stuff up on PS4, but having to pay again for PS1 stuff on their smartphone platform tells me not to be hopeful.
I'm sure Vita PS1 support came after that PS Mobile nonsense and it works with existing PS1 content. Plus, I think PS Mobile games you buy on android work on Vita, but that might be a different storefront than PSN/SEN/whatever. Those PS1 games on android seem like halfway between gouging and miscommunication between Sony divisions, and are the exception. What I imagine happening with the PS4 is that you can only play PS1/PS2 games purchased from PSN, like how the PS2 support is on PS3.
I really like the idea behind virtual console and want it to grow, but resetting the library for each console is confusing. If it launched with Gamecube games, if that's even possible, it might've been exciting again. Then again, one of the big Wii U releases this year is a Wind Waker remake/port. Sony probably made money off the HD collections than simply putting games up on PSN.
