Not a chance in America, the exalted PSP software revival has been an objective failure here, with only Dissidia pulling decent figures since the AAA roll out started this summer. To put this in context, in just 3 weeks Scribblenauts (a word-of mouth, new IP, DS 3rd party hit) outsold MHFU, Rock Band Unplugged, Soulcalibur BD and GT PSP combined so far. PSP games just don't sell outside Japan.
In Japan, maybe depending on when we cut off "holiday games". DS doesn't have anything that huge for Q4 except Layton 4 and Zelda, though PSP doesn't really have any stand outs itself now that KH BBS got pushed to 2010.
