When the PSP Go was first announced, Sony focused much of its promotion of the new digital distribution model on one upcoming title for the portable platform: LittleBigPlanet. Unfortunately, those who bought a Go with visions of downloadable Sackboys dancing in their heads are probably feeling awfully jilted at the moment. See, though the UMD version of the game has been available since yesterday, the customizable platformer still hasn't hopped onto the PlayStation Store. Sony acknowledged the game's non-arrival on a PlayStation.Blog post earlier today. SCEA's Eric Levine later explained in an email to us that though the company planned on a simultaneous UMD/PSN release, unforeseen problems have delayed the game's downloadable iteration. However, Sony technicians "are working on solving that as we speak." We'll keep you updated as to when you Go-getters out there can join in the LittleBigFestivities.
