URC has some new remotes coming out soon (April?), the trc-780 and trc-1200. It looks like both are two-way communication, the trc-780 using RF while the TRC-1200 is Wifi. They also require the MRX-10 to do some of their functionality.
I was wondering how these compare to the mx-980 and mx-5000 remotes.
Since the 1280 is a wifi remote they may be having development issues and thus need more time before it is ready. Or it could be they're having problem getting parts or that they're rethinking the entire design.
