The majority of mechanical keyboards currently sold already deliver NKRO via USB. Pretty standard affair.
The (non mechanical) MS Sidewinder X4 keyboard was the first board I know of to deliver greater than 6+2KRO (although it was limited to 24 keys I believe, more than enough for any two humans simultaneously using every single finger of their human hands, but technically not NKRO).
The Razer BW, all Ducky keybords made in the last 3 or 4 years, all the CM mechanicals, and many others are currently offering true NKRO via USB. Many of them also have a switch to revert to 6KRO mode for compatibility with the standard USB protocol in case you are using it in an older or exotic system.
As for "not needing" PS/2 any more, I don't know about you, but I prefer
PS/2 and am unlikely to buy a keyboard or mobo that does not support it!
You can always slap a PS/2 to USB converter on if you need to use the board at a LAN, or with a laptop, or some other place where PS/2 is not possible, but you can't go the other way around and expect it to work right.
PS/2 being interrupt based rather than polling based, and also having superior compatibility with older systems (especially outside of windows) just makes it a much superior interface to USB for keyboards (unless you need to hotswap your keyboards constantly, but who on earth actually does that?).
