There will not be any updates to the current version, however, there is a C-130 v3.0 in the pipeline. There might be newer glass displays included in that, but I don't know.

You can go to the CAPTAIN SIM COMMUNITY FORUM › 130 Captain 3.0 › 130 Captain 3.0 wish list › FLIGHT INSTRUMENTS, DISPLAYS (http://www.captainsim.org/cgi-bin/yabb2/YaBB.pl?num=1390488558), and add your voice to the wish list for a modernised Glass Cockpit for the C-130 v3.0. ;)
