Top of the line K-3II, Pixel shift, 27 selectable focus points, 8 FPS, 24 Mp, built in GPS
K-70 - 11 selectable focus points, pixels shift , 6 fps, 24 MP, no built in GPS but built in flash
K-5ii - 11 selectable focus points, no pixel shift, 7 fps,
Just a brief synopsis, from memory.
The K-70 gets you Pixels shift and 24 MP. The K-3ii still has some serious improvements over the K-70. But, if you're not interested in the GPS a K-70 might be for you., faster burst rate and more accurate, faster focus, (and a lot of people legitimately aren't) a K-70 might be for you.
As K-3 owner, the only thing holding me back from using a K-70 as my second body would be because though I'd really like to try out the pixel shift function, is the lack of GPS, and inferior AF.
Why am I not recommending the K-3? Two reasons... no pixel shift, and it's not KAF4 compatible. Both the K-70 and K-3II will be compatible with all the electronic aperture lenses Pentax release in the future, the first being the new 55-300 PLM. To me, at this point buying a camera that is not KAF4 compatible will backfire on you, as soon as Pentax comes out with a KAF4 only lens that isn't backwards compatible with o older bodies. If they release something you like in KAF4, like the new faster focusing 55-300 PLM, you'll have to buy a new body when you buy the lens.
Tha K-3ii and K-70 get you ahead of the game on that one.
