[quote name='Treythalomew']Yeah the PSP Go will use the smaller M2 standard for additional memory. If you look around Newegg and Buy.com you will find M2's that are close in price to this.[/QUOTE]
Wow, what an absolutely stupid move by Sony--they should have at least stuck with the MS Pro Duo until PSP 2.
I don't plan on getting a PSP Go any time soon (not for $250, anyways), but I sure as hell am not dumping any more $ into MS Pro Duo's if they're not going to be supported in the future.
Either way, this is a killer deal for people who need the storage. Thanks OP!
