I assume the K-S1 is the "sideways" product (not part of the main product hierarchy, like K-01 before), this one is the new K-r/K-30/K-50 (the mid tier, just below the flagship). So it will probably have the same sensor as K-S1. And maybe we will get another flagship, a true K-3 replacement, WR and the works, sometime later.
Still, I think I will start saving up now

This looks like a great camera and it has that articulating screen I wanted! Wifi is okay, as well, I guess. Maybe can connect it to a tablet or smartphone. Can't wait for more info to come out!
Yes, this should be the K-50 replacement... Some of the design elements of the K-S1 clearly went into this, though it's a shame that the lit up 5 way selector didn't make it... or, hopefully, it's lit up in a more subtle way. Lit up buttons in general can be a nice thing when it's dark, especially the mode dial.
A repackaged, hopefully enhanced K-S1 seems reasonable. I can only hope that they use the hardware in the D5300 for this new Pentax. The Milbeaut used there does a good job with video, it produces clean, aliasing and moire free FullHD content, and the encoder, for a h264 one with around 24 Mbps does a good job (maybe Pentax can raise that, offer 18 Mbps, 24 Mbps and 36 Mbps? Or even more), and likewise the D5300 sensor or something like that, something that is fast enough for full sensor readout at a high enough frame rate. If they'd enable SR (just as an option...) that would be a pretty tempting video package IMHO. It would certainly beat Nikon's and Canon's offerings. If the firmware developers then get some inspiration from the NX1 or GH4 or Magic Lantern...
Pentax IIRC did say that the S line is for experiments, so for example the K-01 would have been the K-S1 if they had come up with that earlier (or maybe K-0x was supposed to be that, but since that experiment didn't go so well they decided to do a fresh start).
Since the camera seems to have WiFi and NFC I think it is safe to assume that the reason is so that you can connect it to your smartphone or tablet. Instead of having to set up the phone to connect to the camera, you just tap together phone and camera, and that should more or less be all. Maybe install an app or so, but the process will be much easier. And being properly built in WiFi the speed will be much better than what a FluCard (or so) can provide.
Pentax has got a lot of things right with this camera, it seems. That's great news.
