MW2 Bug Fix

Is Infinity Ward going to patch all the weapons bugs in Modern Warfare 2? The sights and suppressor of the MG4 are not functional, the FAL's RDS is misaligned, the M9 and M240's silencers are also not functional, and the Raffica's sights are misaligned. Don't these seem like legitimate things to fix, more than the Model 1887's akimbo range?
