Gotta see the games first. Nintendo is usually conservative when listing their specs whereas Sony always exaggerates greatly.
Indeed they do, but the PSP was extremely powerful for a handheld released in 2004, you have to admit. There haven't been any other mobile platforms that could match the best on the PSP.
Just can't let slide the slightest comment that can be taken as criticism of Sony, can you? You just have to paint a rosy picture for the Sony Empire.

Anyways, yes, the PSP's graphical hardware has always been solid for a portable system although it never reached the PS2 level that Sony promised. Any complaints I had about the PSP were due more to its uncomfortable form factor and slow LCD rather than its processing power.
As far as whether any mobile platform can match the PSP graphically, I'd say that the Zune HD has a pretty good chance of accomplishing that. PGR on the Zune HD looks better than the PSP racers I've tried. Of course, it plays like crap with the motion controls so it doesn't really matter to me as a gamer whether the Zune HD is more powerful or not.
This thread is bullshit. Official specs haven't been revealed.
We don't need specs, just look at the screens. Specs don't even tell the whole story. The debates surrounding ps360 is an excellent example. The power of CELL! No, it's too difficult too program for! bla bla bla. Now ps3 and x360 games look exactly alike. 
You must have different consoles than I, because as both a Ps3 and 360 gamer I can tell you without a single doubt that only multi-platform games look alike/have less jaggies on 360.
The exclusive stuff is literally night and day.
And how's that relevant to the discussion? Can't prove shit about which system is more powerful when it's not the same games or the same people working on both systems. Besides, there aren't many PS3 exclusives that most gamers give a damn about.
