I think people are way over anticipating the affect of GT5 and FFXIII. The Slim really has no affect on overall sales, it's the price cut that was important.
We have no idea what the Slim will be like performance wise for at least a few months (early reports of possible overheating on a few units?), GT sales and hype have been decreasing with recent iterations and more competing options are now available (NFS Shift, Forza 3), and FFXIII is only Japan. I have no doubt FF13 will make a nice bump for that region, but that won't help save them in the world wide holiday season.
I still expect more pricing options to be announce by MS since dropping the Elite to $299 is basically costing them nothing and could actually be increasing their profit margins for that machine now. I think the Elite will got to $249 or see some sort of addition before the final holiday season weeks. Arcade may drop to $149 to maintain the 50% cheaper than the PS3 ratio.
