I think they should've made it more AES-ish. That's just too square & boring for me. Also, fingerprints.
...what? This think is extremely SNK-correct, IMO. They nailed the aesthetic almost perfectly, even down to the fake CF originally used on the NGP. The logo is perfect, the joystick looks (I said, "looks") perfect. It's black.
Too square and boring? More like an AES? The AES is literally just a black square slab with a power switch on it. It could hardly be more boring. The most interesting thing about an AES is whatever cart is sticking out of it, and that's why it's so cool. There is no time for chrome badges and rainbow buttons when you are Pro Gear Spec!
That being said, there is still a LOT of room to f*ck this thing up. The price could be stupid, the emulation terrible, the screen shit, the release date a lie...lots could go wrong. Everything we see so far, almost nothing, looks rad as hell.
