It would be great if they came out with a new Touch now, but I somehow doubt it. The Glow only came out less than 6 months ago, I think. I cannot imagine that they would bring out a new Touch model (non-Glow) and not upgrade the Glow version at the same time. So, it seems a little soon for a model upgrade, IMHO.
Actually, that brings up another question - will then eventually only have ONE b&w model - the glow version, or keep them separate as they are now? Since the display is better on the non-glow version, I hope they keep them separate, or improve the contrast on the Glow.
