Here is a list of upcoming PSP games. It's really a slap in the face to the people who believe PSP is a dead platform (looking at you, IGN). People give the PSP way too much crap - it has sold nearly 60 million units, consistently made a profit for Sony, and has, in my opinion, at least 50 games worth playing. That is a resounding success, and anyone who says otherwise is ignorant (can't spell ignorant without IGN - sorry).  
 
Looking forward, we can see that the steam is beginning to run out. Sales of hardware are falling, and Japan seems to be the majority supplier of games for the system. Still, if PSP was to die in 2011, you can't say it didn't have a good run or that it's premature - after all, the GBA barely eked out 5 years. It's now up to the big publishers and niche publishers to work together to bring these great looking PSP games over. Enjoy:
