It Was Always In Sony's Plans To Move Towards A Digital Download Only System.

jp</a>, Sony's planning division top-man Naoya Matsui has confirmed that Sony always planned to release a UMD-less portable. The announcement of the PSP Go puts that plan into fruition:
"We'd planned to release a PSP model without a UMD drive since the very beginning," Matsui said. He further makes his case by stating, "But if we'd simply released the hardware, there wouldn't have been much for everyone to enjoy. We needed to prepare the right environment for it first - things like the transferral [sic] of content with the PS3 and PSN, and PC software to manage content like music and movies such as Media Go."</blockquote>

A case of "we'll do it when the time's right" from Sony then. We're still concerned about space limitations in the new handheld, but hopefully consumers will take to the Digital Download method.
