I'm confident that the K-5 II would address your AF needs.
Regarding the flash overexposure issue: I don't know a lot about it as I use my flashes with manual settings only, but I understand that it only occurs in rather specific circumstances. So you may not even experience an issue with the K-5 II, should you use it with P-TTL flash.
Apparently Pentax claimed that they cannot fully address the overexposure issue on the K-5 (II) because there is a hardware limitation, but again, you may not suffer from it at all.
There is already a
K-3 specific thread regarding P-TLL over exposure and the initial news seem to be good. However, user reports always have to be taken with a big grain of salt, so I'd await further confirmation, if P-TLL exposure were critical to me.
