I love my K-X. Nothing wrong with it. But I just want a bulkier camera, and the K-7 or K-5 seem to fit my wants. Specially the water proofing seal that's a plus for me. My K-X just feels like a toy sometimes compared to the other brands i've used and tested. So far the K-5 is what I have my cross hair on. The batteries on K-5 and the dual SD card sounds really cool and if it comes out with a WR lens kit then i'm more on the K-5 side now... and if the K-5 comes out with a batterygrip, then the better because it's pretty much like the K-7 but only better...
idk if you guys are getting what i mean... I'm feelin kinda sick while i typed this.
