Sony may have put aside plans to offer a UMD solution for PSPgo owners, but a third-party may be stepping up to the plate. Logitech is rumoured to have a UMD drive add-on planned for Sony's download-only device.
CVG cites an unnamed source in its report, pegging an external UMD reader that will let PSPgo owners play their hard copies and "make the PSP a little bulky." Bulkier than the PSPgo camera adapter?
Take the possibility of a UMD add-on as rumour for now, but someone would be wise to make the PSPgo more attractive to owners of the PSP-3000 and its ancestors.
