The new ID-5100 is a dual band mobile transceiver 144 / 430 MHz that will be released in the market (Japanese) in February 2014 in two versions ID-5100 20W and ID-5100D 50W.
As far as I’ve understood from the japanese translation, some ID-5100 features include:
Large high contrast LCD touch screen
Built in GPS (not an option as in the IC-2820H)
Dual DV (simultaneous 2m and 70cm D-Star operation)
SD Card slot
Bluetooth connectivity (with UT-133)
Android application for control. As demonstrated at the 2013 Tokyo Ham Fair.
