i'm sure it's crossed their mind as part of the Playstation Suite strategy
What better way to sell your bare launch year than with staggered PS2 games for Vita / PS3?
Hand pick 10 games and fight to get them on the service :
1st : GT4 , Ico / Wander, etc
3rd : Gradius V, FF12, GTA, Dodonpachi DOJ, etc
Yes, i know i'm dreaming but the biggest value add that Sony could do for the Vita would be to add portable PS2 compatability. If they push it right then you have potential access to the best software library of any console ever published - and then there's PS1 games to... and PSP.... and the Vita games themselves...
(i know there's a ton of problems with this but hey... let me dream)
re: Dongle. I'm just going to come out and say it - the 3DS is a disaster and Nintendo maybe should consider taking it round the back of the shed and putting a bullet into it. Start again - release a new handheld as the Gameboy TWO or something. Seems they've got everything wrong - control dongle - games - Battery life - dat store - backing the 3D horse :/ Sometimes it's just best to put a pillow over somethings head and call it a day
