They might patch the stuff when the game is still within 6 months of the release date just to look good for the potential buyers/fanbase, but after the next COD is announced (roughly a year from BO2's release date) they'll quit caring kinda like W@W & BO.
lol glitches like this i dont think so but every time they find a glitch they always patch it i have been playing the zombies since cod 5 and i guess they patched every glitch i saw
they will most likely patch almost every well known glitch. they should just make a system where records wont be uploaded to leaderboards when there is glitching in a game
