Didn't put so much time into these as usual (mostly because I still reckon we wont get any figures we can use) so they're probably well off. Here's my thinking though:
Don't believe the arcade model will have made much difference to the 360, so we should see a drop to roughly pre halo levels. GBA is on its way out for good so sales will continue to drop steadily. NDS has found a sales level and it's sticking to it. PS2 will benefit from guitar hero I think, but needs one final price drop to eat up the last sales it will get. PS3 will get a small bump from the price drop and 40gb... but not anything world changing. PSP settling above the pre PSP-Slim sales levels. Wii is supply limited and I think we wont see a sales increase until they release the xmas stock next month.
