for the PSP 2 to dethrone the 3DS they would need to
1. Launch at a similar price as the 3DS (within $50)
2. Have the same or better battery life as the 3DS
3. Have a gimmick at least as good as glasses less 3D
4. Be at least 5 times as powerful as the PSP, to make sure that PSP owners feel like it's a worth while upgrade and 3DS owners see it as a more powerful machine and keep it more powerful than iPhones for a couple years.
5. And this is the most important launch with at least 3 entries in million selling franchises, the 3DS has Nintendogs cats, Super street fighter 4 and Professor Layton .
6. Games within a year of launch to match The Legend of Zelda: Ocarina of Time, Rabbids Travel Time, Kid Icarus Uprising, Metal Gear Solid Snake Eater, Dead or Alive Dimensions.
7. A list of upcoming games to match Kingdom Hearts 3D, Mario Kart 3DS, Mega Man Legends 3, Animal Crossing, Paper Mario and Resident Evil: Revelations. opps forgot Time Travelers that game looks interesting and this list is likely to get a whole tone longer as I am sure that more games will be announced soon.
I totally forgot Professor Layton vs. Ace Attorney
