You know what nobody’s talking about? The new SD cards are ridiculously expensive, and you can barely find them online. And when you do, it's usually just the 256GB version. Games for the S2 now range from 20 to 120GB, so you'll end up in an even worse situation than the PS4 had at launch.

You're the only one I see talking about it and it's going to be a shit situation, 1TB SD is going to be premium price and 256GB is going to be nothing, some may even settle with multiple 256GB SDs to "make up". This is PSVita Memory Card all over again.
