COD is the only bundle left other then the UC3 and FFXIII-2 bundles that favors any consoles.
the Sky Rim, BF3, and Batman Arkham City bundles won't help PS3 or 360 much.
i think the GEARS boost is done for the 360 and PS3 will start to outsell 360 again for Oct.
Nov. favors MS only because of BF3 and COD, even with UC3, FFXIII-2, and the BF3 bundle for PS3.
nothing in Dec. so its anybodies guess, but over the yrs its favored MS and ninty but not every yr is the same.
