The 7000 having a tinier sensor is going to make shooting shallower DOF harder and the Pentax K-3 will deliver greater detail having an extra 12 Megapixels. Higher resolution can also allow you to crop shots way more aggressively. The older 7000 is going to be behind with regard to sensor technology.
