I don't know, the 'new processing engine' sounds good but could only apply to JEPGs. For RAW, it would still be identical to the K-5 with a newer sensor.
Your strategy sounds suspiciously like the canikon route of dubious upgrades and missing features that don't always justify the price differences.
Maybe that is the only way to go from a business point of view.
