Chance: yes, even with odds from 1 against 1,000,000 it stills one chance...
More seriously sony could beat the 3DS with the PSP2, but they have to play they card extremely well because Nintendo looks to have play their cards even more better than with the wii and DS. They have the wow factor, hype and support for 3rd party from start.
The only draw backs for the 3DS could be the sale price (250 USD/Euro) and maybe a little the battery life (but if it's equal to the DSi as certain people pointed, then it was not really a problem).
The rumored Psp2 seems to be a monster in power... So you can expect a lower battery life (this couple with the big Hi-res screen) and also a pretty expensive price for the powerful CPU/GPU, RAM, Hi-Res big screen and big battery.
Also these elements could indicate that development cost for the PSP2 would be much higher than the 3DS, so games are unlikely to be cheaper, they could be at the same price a best. But as the PSP2 haven't been officially announce now, this is just conjecture. Just hope for sony they won't pull off a PS3 again (every expensive handheld: 350 USD with few games at launch window).
But we must first concentrate ourselves on the way to entertain people, for video games to live. Else, it's a world where sales representative will win, which has as effect to kill creativity. I want to say to the creators all around the world:"Courage, Dare!". Shigeru Miyamoto.
