Sony sensor in D5200 is different than D3200 and it's same or updated version of NEX-7 as per some discussions. About AF, lets accept, Pentax will not be able to touch Canikon in near future, unless some miracles (but that too doesn't happen now a days).
I love and have been with Pentax but com'on, Pentax needs to catch up. Now if you think from a new buyers perspective, It simply does not make sense for a new buyer to buy Pentax K-5 II at same or price while D5200 has more resolution (and that translates on more details if it has same/updated sensor from Sony), better AF so definitely more keeper and certainly more lenses to chose from. Also, this is an alarm for Pentax, D7000 update likely to be very soon.
I don't know about what class k-5 II is and may be it does not matter for many of us, I am just talking about a better camera. My personal opinion!
As has been said before, the K5 II is not the competition of the D5200 and people looking for the features that the K5 offers will be poorly satisfied with the D5200, even if it really did offer a huge improvement in autofocus and sensor capability over the K5.
As far as auto focus goes, at this point, Pentax does have two issues. Tracking auto focus, which is not there yet, but is significantly improved. And size of auto focus points (Pentax's are too big). But I doubt in most situations, with a comparable lens (say a Sigma 70-200 HSM) on both cameras you could tell that much of a difference.
Second, as Rawr says, the increased resolution is probably not going to be apparent in most situations. It requires low iso, good lighting, a high quality lens and precise auto focus. When all of those things come together, you may see some improvement in resolution, but in real world situations, the 24 megapixel sensor is not going to give much resolution improvement over the 16 megapixel sensor, particularly not when you consider that the D5200 users will be using kit lenses and consumer telephotos. All they will see is bigger files and a little bit less dynamic range and high iso performance.
To me, the big differences between the K30 and the D5200 will be in terms of video capture (the D5200 will be better) and in terms of still photography (K30 wins). Having a 100 percent pentaprism, 2 control wheels, sealed body and features like Tav mode just make a camera so much more usable for still photography. I wouldn't consider a camera body that didn't offer those features.
