Q: When will / is there a beta for Crysis 2?
A: We don't know right now. It was mentioned as a perk for joining the site, but was quickly removed from the list. Currently there is no news on an upcoming beta.
Q: Will there be a console editor / mod tools / sandbox editor?
A: No. Crytek themselves have said that the requirements for sandbox 3 are HIGHER than the PC version of the game. They actually said that the "minimum requirements" for the EDITOR are a Quad core CPU, 4gb ram, an Nvidia GT-200 series (or ATI version) GPU and an x64 OS. Neither the playstation 3 OR the xbox 360 come even CLOSE to these requirements. Crytek COULD announce an ultra-light version of the editor, similar to Halo's Forge mode, but it is currently unlikely. If you see people referencing Far Cry 2 as a reason for Crysis 2 to have a console editor - this has no grounds. They run on two completely different engines.
Q: What are the PC requirements?
A: No idea. Crytek has said that if you can run Crysis, you can run Crysis 2. However, no news on what settings or resolutions will be possible on a system with that spec. The editor has been recommended to be run on systems with a Quad Core, 4gb of ram, an Nvidia GT-200 series card (or ATI version) and a 64-bit OS. This has been confirmed as MUCH higher than the actual game's requirements.
Q: When does Crysis 2 come out?
A: It has been said to come out Holiday 2010. This was confirmed MULTIPLE times at E3, as well as multiple Crytek websites, like gamesas.com, SOSNewyork.com and the EA store website.
Q: Has any PC footage been shown so far?
A: Currently there is no game play footage from the PC version, but a cut scene rendered entirely in-game on the PC has been shown. This video was the reveal for 3D support in Crysis 2. Please note, the game play at E3 was TECHNICALLY on the PC, however it was running on the same visual settings the Xbox 360 will have. This is likely due to stability or performance, although there is no official reason.
Q: Which version will look / run the best?
A: Crytek has said that the PC version will look best out of all 3 versions, simply due to resources. The consoles have been said to look "similar", each with their own strengths and weaknesses. Crytek has said that the PS3 version will run Physics calculations slightly better, due to its 'Cell' CPU, while the Xbox will run shader calculations slightly better due to its slightly better GPU. As for over-all appearance, there is no official data, as no high-quality screen shots of BOTH PS3 and Xbox 360 versions have been released (depicting the same area).
Hopefully that will answer many of the questions, as right now on the "General forum" area there are 3 threads on console editors, 3 threads on the beta and a ton more on release date and PC requirements.
