I really enjoyed Crysis 1 & 2 (especially the story) on the Xbox, but I wasn't happy with the lack of continued support for bugs and issues in regards to the online multiplayer, so for me to even consider purchasing Crysis 3 at release I want some sort of confirmation that continued support will exist at least for quite a while after the game's release. Otherwise, I'll probably pick it up sometime down the road when its price as dropped significantly just so I can play the story.

Exactly. I want support that lasts for more than 3 months.
