If you read the comments for the new image of the MGS Collection on the Vita, you'll find me bitching about Remote Play and what not. So as to not whore the comments there, I'll continue it here.

I had completely forgotten that the PS3 existed. While making the question ("Why does this Vita collection exist if I can just use Remote Play and stream it?), I had forgotten that in order to do that you need to, in fact, have a PS3. I am truly sorry for that.

And then it hit me:

a) The PS Vita is being treated with equal importance to the PS3. Think about it, it has Trophies and Friend Lists, and now it has not a port, but a version of the HD Collection. That means that this could be the first multiplatform title in which the portable and the console version are exactly the same (although the Vita lacks Peace Walker, IMO that's for the better)

b) We will probably see Portable Collections. As in "Play the first two inFamous games in your PS Vita! Buy it now, inFAMOUS: Portable Collection!". Man, I should work for Sony :D
