That puts the NGP's game media storage size between that of the PSP's, whose UMD discs range from 900MB to 1.8GB, and the PS3's, whose Blu-ray discs hold up to 50GB, though "many PS3 games" (i.e., multiplatform titles) remain around 9GB, thanks to the Xbox 360's DVD-ROM size limitation. Of course, as pointed out in a second slide (afer the break), this leaves the NGP with far more storage per game than a "10MB phone game."
But that's not all! As previously suggested, the NGP has another storage option, simply called "removable memory" in this presentation. "Cards will be large to support a variety of downloaded content," the slide says. This includes games available over PlayStation Network; and, thankfully, Sony says it's implementing a "single submission for both formats" to streamline the process of getting games approved for both card-based and downloadable releases.
We're hopeful this streamlined process obviates current embarassments like the continued absence of high-profile games in the PSN catalog of PSP titles, which has crippled the appeal of Sony's PSP Go handheld.
