What I really want to see again and what made Crysis 2 feel so different like the first one is that there is no Super Sprint . I loved it to run in incredible speed trough the jungle and from one cover to another or towards enemies, and I think this is something they need to put in in the game again. (I also miss the suit saying "Maximum Speed" and "Maximum Strength")
ditto, there was a suggestion of this separation of speed and strength from early previews, but it certainly doesn't seem so from the latest e3 gameplay footage.
this concept of suit mode "multitasking" appears to be what crytek is running with as the better gameplay option. I personally preferred the extra feeling of control, and the satisfaction in gaining skill in quickly changing suit modes on the fly from the N1, rather than the auto-pilot N2
