What is next after the HTC S730; maybe not the ordinary slider

You have come to expect slider phones from HTC. The HTC TyTN (AT&T 8525), the TyTN II (AT&T Tilt) as well as the HTC730 Smartphone. We all know that there are new models on the drawing board but what will they look like? I would hate to see the large displays shrink and the QWERTY keyboards are so handy go away in any form.
