Tsk,

Firstly, The probabilty of them upgrading the graphic processor is close to nil as by doing that they are shunting the old version of NDS. And from all accounts of what Nintendo have been doing, Graphic is the least of their concern.
They might take out slot 2 or readjust the location of the speaker and mike to provide a slimmer top screen. But that is just my 2 cent

As for courting girls with psp or ndsl. Good lord. do u get the device to play game or to "attract" girls? And furthermore, its not the device that attract people. Its the game.

My gf enjoy Loco Roco on PSP and Taiko No Tatsujin on NDSL. She play both console liberally and from time to time. I did question her which one she like and she prefer PSP due to its better graphic and nice design.

Anyway, the thing is this. They might redesign the NDS but when will they launch it. Is another matter altogether.

And if you are planning to get an NDSL now, Just do it. There is no reason to hesitate. NDSL as it is now is superb. And for all you know, the new NDS might not be as nice. Take Game Boy Micro for instance. That one is the latest in GB line but it is anything but great and a lot of people prefer SP over Micro. This MIGHT happen to NDS too.
