While yes it is at a somewhat slow (but steady) pace most months, console wars are won and lost in big bursts. More ground can be gained and lost in a month between Thanksgiving and Christmas then in the entire rest of the year for instance. Also big release weeks make large dents, and there are a lot of those coming for the PS3 (I really think that Little Big Planet will be more of a game changer then MGS4 since it expands the audience in a much larger way).
The way it really seems to be is a weekly advantage of 30k to Sony with occasional jumps to 100k or more with big releases. If that continues (and price drops on the 360 don't seem to be changing much) the eventual 299 price drop and big releases will easily let the PS3 overtake the 360 by the end of next year when it will still matter. All thats left is the NA market, The PS3 is ahead of the 360 throughout the rest of the world.
Additionally the pace of PS3 sales have been accelerating rather profoundly, while the 360 sales have more or less stagnated (and will almost certainly decrease as the 360 hits its saturation point of around 30-35 million consoles at which point almost all of their core audience will have one just like with the original).
The only big weeks for the 360 on the horizon are GOW2 week and Fable 2 week. Unfortunately most of the audience for those two games bought a 360 long ago with Halo 3 or Gears of War One. There is no real week you can point to in the upcoming months and say "that will be a good week for the 360" while there are at least a half dozen of those weeks for the PS3.
