Is the Polymega packing heat? Lightgun support may be announced at E3 2019

Polymega has been hard at work trying to set their CD-centric clone console apart from the competition. One sure-fire way to do that would be to add light gun support, which is what Polymega HQ appears to be teasing on social media.
The Polymega is a CD-based multi-system “clone console” which supports games from the SEGA CD, PlayStation 1, Neo Geo CD, SEGA Saturn, PlayStation and the TurboGrafx-CD. The Polymega is also unique in its “modular” design, in which players can purchase additional hardware expansions to play cartridge games from the NES, SEGA Genesis, SNES, and TurboGrafx-16.
Will we finally be able to play games like Time Crisis and The House of the Dead on a modern HDTV? It looks as though we don’t have to wait long to find out, as E3 2019 starts on 11 June.
