Please sign this petition if you want Insomniac (or another developer) to make a R&C collection on the PS3. It would be a collection of all the PS2 R&C's on a Blu-ray disc for PS3, HD-ised for the PS3. Insomiac has said that
It's a cool idea, if there is enough support for this sort of thing. If SCEA wants to do it, we'd support a dev taking it on. (via Twitter)
So sign the petition if you want the collection, and maybe it'll happen!

Well I signed it anyways, even though online petitions are almost always unsuccessful I think :S but yeah I support the idea though for the future, so that later on you wont need a PS2 just to play the older games.
I will, and I really hope it works, I really want to play them.
signed it! 
I signed it, too. I doubt it'll work and this came around after my thread of announcing that they were giving those user friendly survey thingies, so I sort of think this petition is pretty pointless.
OMG that would be awesome seeing the old R&C games as a collection for PS3 but too bad it's unlikely
