Where will Sony take the PSP2?

As far as I can see, the PSP has 4Mb of embedded DRAM, which is split into 2 seperate chunks of 2Mb, one if dedicated to the GPU while the other is dedicated to the Media Engine.  The PSP originally comes with 32Mb in DRAM for the CPU, but can earmark more memory from this 32Mb for the GPU if it needs.  The PS2 has 4Mb of dedicated GPU memory which is double the PSP's and it can also earmark memory from the main onboard 32Mb for graphics processing as well.

The only difference now, is that the PSP Lite comes with 64Mb of main board memory, doubling what it has in the original PSP.  This is supposedly earmarked for game file storage to make games load quicker over the course, but I reckon all this 64Mb can be used for graphics as well.

So theoretically, the PSP can call on more GPU memory than the PS2 if need be.  Also the PS2's video resolution is significantly higher normally than the PSP's.  So effectively, the PSP only need to render graphical information at roughly half the resolution of the PS2, which means it should be able to create more lavish 3d environments compared to the PS2.
