MMR Software update will be issued soon. They will be a binary file which will have a utility application to load onto an SD card (which most PC's have slots for SD cards for camera, etc support). Then the SD card fits into the backboard box, and loads the updated software.
As of right now, we are waiting for any additional feedback, and tentative software update would be in the May timeframe, and the primary 'fix' would be to address the screen transition issues that occur in some frames. We will be incorporating any additional issues, but so far they are few and far between.
