I hope they make it a constant f4. If it's another cheap, variable aperture telezoom, I'll probably pass. Since the excellent SMC F 70-210, Pentax hasn't done too well with those.
If it was a conservative zoom range, say 50-150, we could probably be confident that it would be a good lens. At 50-200, it is harder to predict.
