What concerns me about GRID and all the games (and graphics application in general) on the cloud is that it doesn't look like a scalable solution... I mean, Amazon has already a lot of GRID 1.0 servers and services that make use of it by now. But GPUs evolve fast... There will be a moment (soon) when a single GPU instance on GRID 1.0 won't handle a modern game, than what? They will need to replace all the server hardware every time this happens? It doesn't look like a viable solution... But I'm just guessing here.
