I was watching the crysis 2 limited edition trailer, and I noticed above each of the "classes" there was a name. Possibly the Developers in-game names?

Here they are:

Skuf
Yer Maun
Perkuleez
XPheonixRisingX
That Kid Chris

also:

MiloMilo
MrComerFord
From hologram decoy section.

Crytek probably just made up names, it doesnt necessarily means that they will play with those names 6 months from now...

Talon95 is right, names could have been used just for the demo, If they appear in my game, I know who to go after !
