Rumour: PSP2 to use Mini Blu-ray discs

The current rumours say the games are almost PS3 level that means that the PSP2 is in the same league as the PS3 just like the PSP was in the same league as the PS2, as in much weaker but games look comparable thanks to the low screen size. Oh and you do realise almost all PS3 games are rendered at 720p or less right? And The PS3 has a texture fill rate of 13.2 GigaTexels per second vs the PSP's 664 Megapixels/s that's over 20 times so textures 4-5* bigger for the PSP2 given the speculated power is conservative I think, add in more complex models etc and you need a significant amount of bandwidth if you don't wan't long load times...

The games may look "comparable", but the PSP is definitely weaker than the PS2.  If you actually look at the games side by side (say for instance, GOW2 vs GOW:GoS), you'll see that the PS2 is much more powerful when it comes to texures and polygons.   Even using your texture fill rate comparison, the PSP has 664 Megapixels per sec, while the PS2 has a max fill rate of 2.4 Gigapixels.  But you have to remember, these are just the max specs.  In actual excution, these are never met.  The PS2 rated fill rate when textures are added is actually 1.2 Gigapixels, or roughly twice as fast as the PSP's MAX rating.

So really, the PSP could much more accurately be called a PS1.5.  I think the same will be true for the PSP2.  It will be much closer to a PS2.5 than a PS3 in terms of power.  In fact, given that all games will built around running on such a small screen, the fill rate for the PSP2 may only need to be as fast as the PS2.

I know all that...

and if you did the math you would find the 4-5* PSP texture rate of the PSP is 2.6-3.2GP just a bit more than the PS2 all you are saying agrees with what I did except the parts where you think I am wrong... 

There is still no way SONY are going to use mini Blu-ray and the slight chance of a blu-laser UMD variant would be inferior in bandwidth, latency and capacity to a flash based medium and also use more power be more likely to break due to moving parts and increase the cost of the PSP2 it's self, bottom line is that any disc based solution for a handheld is inferior to a flash based one and it would be stupid of SONY not to go for a flash based solution...
