Unfortunately I'm rubbish at predicting Access' future releases.
However, it's been five months since the last full/stable release. Most of the main bugs have been ironed out, which is great. As such there have been no beta releases in the last five months either.
They have a nice clear run until NAMM in three months time.
Of course they must still be working on something.
I'd say either a new OS to bolt onto the TI, or there's a possibility of an entirely new TI|3 (given that the TI|2 was a refresh of the TI|1 and that there are no outstanding bugs for the current mature TI OS). Perhaps the Snow may even see a new version.
But my guess is as good as yours, and my second guessing has always been poor in the past. We'll just have to see.

A ribbon-controller or XY-Pad might be nice, too, please! Thanks!
