More than a bit, OB1... but yes, it is speculation... but it's informed speculation. They are basing it on facts. They know how long modern batteries last... and today nothing pushing power (and using that power) like the PSP could last 10 hours, I think, with the kind of battery it has. As they say, it might well get 8-10 for MP3s, but for games? That is very doubtful, since they'll be pushing the thing and draining its power...
