Squeak,
Yes I've played it at Winter NAMM. Both the 76 and 88 version were on display. They are both very nice keyboards and look much more expensive then they are selling for. Basically, they are both like the PSR350 but from what I remember, nicer buttons, display and better sounds. These keyboards will be shipping in July or August.
