There are traces of possible new underlying hardware in 5.1.0 update bundle. Two new development boards are mentioned: first has Wi-Fi only or Wi-Fi + 3G variants, second has just Wi-Fi only variant. Each of them uses cyttsp driver (Cypress TTSP capacitive multi-touch screen support). Also one of software subsystems expects 210 DPI on screens of these boards (instead of 167 DPI on current KT screen).
UPD: ah, cyttsp driver had been mentioned in 5.0.3 KT software or even earlier. But all other traces were introduced with 5.1.0.
