Koller explains that this is because of "a larger power draw with the brighter screen." Aha, just as I expected. Well, "20 to 30 minutes" of a shorter battery life isn't that much of a drawback, methinks. And for those who think that it's the end of the world because of the decreased battery life, Koller confirms that there's still going to be other options out there:

That's going to be off-set because we're still going to have the extended life battery that's still available for the consumers, so they're still going to get the 8 to 10 hours out of that battery. Or the battery that comes with the PSP will now be right around three and a half to four hours.

As for other components, the PSP-3000 model will have the same compatibility with the Slim accessories - they want everything out in the market to work with the PSP-3000.

It's also been confirmed that the Slim will be phased out eventually. Koller says production of the PSP-2000 will cease by September.
