Welcome back!
An evil Pentax K01 has been announced a few days ago (see the front page of this site or google it). Well it is evil with no "ev", so I guess this makes it an "il" camera. It has K-mount and K-5 sensor.
What happened to your K-7?
K-5 is an amazing camera and personally I would pick it over the K01, no doubt. I have it since December and I can not stop being impressed by it. It is the first time ever I do not feel the need to upgrade to something "better".
EVIL vs dSLR: as far as I can see, the general consensus is that dSLR have an edge over EVIL or mirrorless as they are being called now. Mirrorless imho is the way to go for those who compose with the LCD (or need EVF vs OVF - though many mirrorless have no viewfinder what's so ever), value video over stills or prefer the smaller formfactor (some mirrorless as the K01 aren't really smaller though)
As for waiting for the new K dSLR: I'd keep the K-7 instead if you still have it and invest in lenses or buy the K-5. I do not like to pay huge premium for the newest tech with newest bugs
