Answer: Nope.
Here's the thing, Crysis 2 has a connection to Crysis 1/Warhead's story (not so much Warhead but still), yet the connection is not super strong. Because of this weak connection, it's easy to pick up the basic story in 2 for console players. Plus, maybe they might even explain what Crysis 1 and Warhead were about when the game comes out.
What you console gamers might miss out on in Crysis 1/Warhead are possible twists or easter eggs in 2 that make gamers go "OMG, HOW SWEEEET!!!!!!!

!!" And also the gameplay in the games themselves (of course). Crysis 1/Warhead would never work on consoles unless a full remake was done. With prone, lean, the suit wheel, and everything not being streamlined, console gamers will HATE Crysis 1/warhead cuz of the controls on a gamepad.
They don't need to remake Crysis 1/Warhead just port them over to 360 and PS3 like everybody been doing to every other game series that been out on the market, just change the controls for the 360/PS3 tho.
It's easier said than done
