$10.53 exactly. The PSP1000 will go down $10.53. Exactly .

Sorry for the sarcasm, but how on earth should we know? Indeed, the price might not come down at all in some stores or sites if sales are going along just fine at current prices. If you want a cheap PSP, go buy one second hand. If you don't like the price of a PSP no one if forcing you to buy one.

If the connections are similar enough and the screen is the same size, perhaps. May require some skill with a soldering iron (and a new casing or a cutting a casing with a dremel).

But I've heard the new LCD has slightly larger power demands (John Koller - http://uk.gamespot.com/features/6196930/index.html sourced from - http://en.wikipedia.org/wiki/PlayStation_Portable_Slim_and_Lite_(PSP-3000_series) ) and that may mean different connections.

Additionally there seems to be some questions over how good the new screen actually is right now to -I'm keeping an eye one the PSP 3000 page on wikipedia, it seems to be getting alot of new content on it now
