Probably. I wonder what else they can improve from the DS Lite now. Dont want it to be smaller. Zzz.
Well, you pretty much have your answer there. As colin has said it. The PSP is rather boring. Just the usual Directional button combos and the Square, X, O and Triangle button. It doesnt offer that much. Plus, the PSP has a very very bad gaming drought.

Yes i agree with you , for fighting and racing games , personally the game will be more fun if the graphic is better for these 2 genre of games.

Personally , i prefer NdsL as i had both before cos firstly i prefer the DS games more interactive and fun yet addictive

PSP never strikes me addictive at all since i had it for almost 5 months and tried as many games as possible

And also both tried to play it with online , DS wins completely in this 

p/s  PERSONAL THOUGHTS

That's a different reason altogether. Tekken is an exclusive game for Sony consoles, and Pokemon is the same in turn for Nintendo.

Don't get me wrong though, my friend recently loaned me his PSP for a few days, and I managed to try a few popular games, namely Crisis Core, Patapon, the Burnout series and the Monster Hunter series. There are a few good concepts there as well, and the graphics just kicks the DS off the ledge.

About the build quality, by overall it's fine but the compartment where the battery is kept should be seriously amended. I like my handheld consoles grippy and solid without any creaking sounds or 'loose' areas, and the engineers of Sony just had to put a shaky cover at the right hand side. That, seriously put me off.
The DS will never be a platform for fighting games. Doesn't anyone notice how hard it is to get the NDSL to register directions 1, 3, 9 and 7 properly?
