You are correct. On spec my info is that this has substantially improved. Tests will tell. That and early adopter feedback.
Overall the K-5 looks to be a K-7 upgrade, their flagship, top-of-the-line animal designed to go head-to-head with the same from Canikon (like D300s) and Sony (release du jour), and MSRP US$600< their FF offerings, especially at street price. The market is waiting to see where Canikon come with their FF line-up. With the Yen high, I suspect no budge in pricing from Nikon, but the D700 may notch down a bit and stay in production closer to US$1,900 if the come out with a D800 as expected. Just a rumour and hunch. That will put pressure on the flagship APS-C's to drop prices quickly. The K-7 lost as much as 40% off MSRP in 8 months. That's pretty good. Look for that again.
There were 3 main areas the K-7 needed to improve on:
1) High ISO and noise performance. K-x or better, please. Looks like on paper they went there.
2) Video. Also looks like they went there. Important for broader sales.
3) Better AF. Again, on paper, apparently a lot has gone into this, long seen as the Pentax weak spot. Tests will tell.
As for lenses, I have heard of 3 in the pipe, but only 2 to be released soon, a zoom and a prime. Both DA L. I think the DA Ltd line-up is done because APS-C is a question mark, so no major upgrades like WR, SDM, etc.
We could be surprised. My info is from the distribution channel, so something might come from the floor at Photokina. The stuff I do know about is in preview now and is being loaded into shipping containers for Christmas season sales.
One thing I have not heard of from Pentax is AF capability with video. Sounds like both Nikon and Sony are on this. That's going to be an interesting tangent for performance spec.
