NGP games will come on 2GB and 4GB cards, with room for save data, patches

This slide, shown during Sony's Next Generation Portable GDC panel, shed some light on NGP's still-mysterious storage details. Unlike the experimental PSP Go, the NGP doesn't sport any internal storage. Things like save data and patches will be stored on the actual game cards themselves which, notably, will be offered in both 2GB and 4GB varieties, with 5 to 10 percent of the storage allocated to the aforementioned data. On a 2GB card, that leaves 1.8GB to 1.9GB for game data; on a 4GB card, that leaves 3.6GB to 3.8GB.

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.
