Just wait for 2-3 months for the picture to be clearer on what Pentax will release.
Info on the K30 has already been leaked, and it looks to be idea (K5, but cheaper and lighter)
Who knows,Pentax might pull out a FF at Photokina?
2 recent photography trips have made me very grateful that I am using Pentax K5 for the small DSLR bodies and lenses, while not sacrificing performance (AF speed; DR; ISO; lenses).
For family and real world shooting, I don't think D800 is the way to go.
Heavy, large, less forgiving to lens, focus/movement errors.
If you downsize those for great looking picts, why punish yourself with the weight and size in the 1st place.
Of course, it will always sit as a very tempting 'WANT' for most photographers.
Personally, I've been using my K5 or m4/3 G3 for family shots with the G3 taking up most of the work when photography is an after thought. (ie. Day out shopping; Morning walk in local park > breakfast, etc)
