I interpret your question as, "Will there be a 7100 with a full QWERTY keyboard?"
My answer is that I don't think so. Actually, some people find it easier to type on a BlackBerry 7100 series than a TREO -- surprising but true. Give the 7100 keyboard a test. It's because the TREO keys are too small for some people.
I prefer the full size QWERTY keyboards, like those found in the newer 7290, 7250 or 7520. (The three favourite models to get these days, IMHO)
You probably saw the model 7100 series BlackBerries:
