Just to be clear and not too smooth brained - " How about an updated Wi-Fi DCS remote for those of you that prefer the dedicated tactile hand-held? It will be compatible with the existing WIU, the new WTIU, and the WZ4K (way down the line)." - this means the new remote when available will talk to my existing rev I tiu as long as the wiu is plugged in. If I blew that understanding someone please correct me, because I think its great!
To me one of the best things has always been that when there is no dcs signal at all, you still have a conventional loco that can do the important things from a conventional transformer, ie. move, change direction, horn and bell. The current technological state of toy trains we are experiencing is amazing. I describe the dcs control system to those outside the hobby as being able to do just about everything but make the loco stand up and dance.
