From what I remember there is at least one weapon in each category (besides Etc. and Melee) that is still avalible for one day durations (One NX and One GP). The Support category (Frags, mines, chemicals, flash, HBS's) still is the same.

The AR's have two NX weapons as opposed to only one, which the two are the M416 CQB and the G36E Valkyrie.
