I'll add my current "buying decisions" to the list in case Pentax is listening:
As far as the rumors of a mid model - K-x upgrade with focus points and top LCD - I would buy one today. I am darn close to buying a K-X regardless. If the price comes down just a little I may.
A K-7 with K-x sensor performance coupled with 1080@30fps and 720@ 60fps video would make my wallet cry. I am a video professional. If it had a 1080@30fps mode I would own a K-7.
The Canon 7D has been quite interesting to me. I just can't justify the investment in glass HOWEVER I can rent just about whatever I would want very reasonably around here.
If the 7D was closer to $1200 in price I would probably be selling off all my Pentax glass to get one - and rent lenses for a while. I'm sure the ergonomics would drive me nuts, but having rented Canons many times before for pro gigs with extreme Autofocus needs I've always been able to get work done with them.
I am still shooting my personal projects with K100D - that's how cheap I am. I'm really in need of something desirable to open my wallet back up.
If I could demo a K-X here I'd probably buy one already.
My employer wants to buy a few sub $1000 bodies too, and It's killing me that we can't rent Pentax lenses around here on short notice. I might have to use T2i at work now.
Pentax has done a very good job of keeping me loyal to the brand in anticipation of that next model. Unfortunate for both of us- I haven't bought anything since my K100D. If the K-X doesn't break that cycle I sure hope the next model does.
One of the things keeping me brand loyal is my collection of M glass. Do any of the current models support full functionality with M glass?
