We're not sure which part of "you can buy a new, larger battery from Sony to extend your gaming time
" John Koller didn't mean, but evidently we (read: the world) had it all wrong. In a recent posting from the Director, he "clarifies" things by asserting that "the new PSP
will have equivalent battery life to the current PSP, about 4 to 6 hours for games and about 4 to 5 hours for UMD videos." He continues on to affirm that the new, brighter and altogether lovelier display
does suck down more power, but Sony's dutiful engineers apparently managed to "reduce the power consumption of the overall system" in order to counteract that. At this point, we'll just wait for real world battery tests before believing anything.
