I'm not saying they are incompatible. All I'm saying is where my priorities are. Ain't looking for a FF, so the K-1 is not for me, but certainly looking for a smaller sensor camera. A quick release camera won't make me buy it. A (very) good AF system will. If the camera ALSO has the quick release grip may be a bonus, but not a buying trigger.
And I didn't say you did, although I was pointing out that the mooted new camera may well have better AF than its predecessors, but all we know about is the new grip. We know nothing about any other detail of the camera itself, but I wouldn't expect the grip to be a major selling point, as interesting as it may be, in itself, for those who care about such things. We don't even know where this new body will sit in the APS-C range.
I also mentioned the K-3, as well as the K-1. Now, I haven't had a K10D, but I have had a K20D, a K-5 and a K-3, and each model has brought with it a noticeable improvement in AF (among other things). I expect the K-3II's successor to have some of the K-1's improvements, too, including AF. Not too long, now, and we'll all see whether that's the case.
