Normally, it is difficult to see the difference between sensor dimensions simply by reading through specifications. The pic below may provide you a better sense of the sensor dimensions in the K-3 II and NEX-3.

Plainly, both the cameras have got the exact same sensor measurements albeit not the same MP. You should count on the Pentax K-3 II to give extra detail with its extra 10 Megapixels. Higher resolution will enable you to crop shots much more aggressively. The newer K-3 II is going to have an advantage with regard to sensor technology.
