I do not know about Coinomi, but people say that tritium could be released soon, although it's not officialy confirmed by the NXS team.
And it's not the only interesting rumour out there

Ron Paul is going to speak at the Nexus conference. Exciting few weeks in front of us! 

Happy to be on board. It's always nice to find a not widely known, undervalued coin with active devs and a very interesting idea behind it.
