(Disclaimer: the free thing is totally dependent on you having PlayStation Plus by the way. In other news, you should probably get PlayStation Plus. I am a big fan of PlayStation Plus and its free video games.)
Anyway, on to the Super Meat Boy on PlayStation thing. It's happening, only four and half years after its initial release on the Xbox 360 and PC. Yes, it's been that long. In fact by the time the game comes out (currently a vague "later this year" according to the announcement post by Tommy Refenes of Team Meat).
Also according to that post: all the fernickity legal reasons why Team Meat couldn't release Super Meat Boy on PlayStation consoles have now somehow evaporated, allowing the game to finally make it across to the PS4 and PS Vita. This is a good thing.
It seems silly to get excited about a game that came out so long ago — a game I already played to the absolute death I might add — but I will be playing Super Meat Boy on the PS Vita. In fact, that might be the best place to play a game like Super Meat Boy period. The whole free on PlayStation Plus at launch thing is just the icing on the cake.
