Before the end of the year, a new SIG MCX VIRTUS carbine replica should hit the stores. Formally, the replica will be manufactured by SIG AIR, therefore there isn't any kind of license involved. The real replica's true manufacturer however, is VFC which also produced the SIG MCX replica for Cybergun at the time when it had the appropriate license. In the photo below both VFC products can be seen. The SIG MCX VIRTUS in the foreground, the MCX made for Cybergun slightly above it.
A few details of the new replica:
