Do you want whatever new camera(s) they announce at Photokina? If you're waiting for the mythical Full Frame, you might even have to wait a little longer than that - who knows?! Remember, unlike Canon and Nikon, Pentax leaks ("rumors") often don't occur until only a few weeks before the official news.
Anyhow, if it's the K-3 you actually want, and you need the Battery Grip (as I do) it sounds like a good opportunity to pick one up. But my common sense instinct (I have no inside information here) is that the K-3 will have an upgrade/replacement around (or shortly after) Photokina - partly because the mirror-flap issue has garnered a little too much attention, and the best way to get over that would be to simply introduce an new model. Whether it's called a K-3 II - or something else - doesn't really matter.
