PSP-4000 Rumours Heat Up Again Due To PSP Go's Slow Sales

With the announcement of the Nintendo DSi LL / XL this morning, the PSP-4000 rumours have started up yet again. This is likely because the PSP Go sales have been pretty underwhelming so far - similar to the PS3 at launch - because of its high price tag. PSP-4000 will bring back the UMD, but I doubt it'll sprout another thumb stick.
