I'm not sure if this is the right place for this but.....

I have been looking into getting a wireless system for my guitar. I was at the local guitar store last night and the guy there told me that after T.V. goes to digital in February that the UHF/VHF units will be pretty much useless and that I'd have to get a digital one. Does anyone know if there is any truth to this?
I don't think so. As long as it's still transmitting and receiving in analogue signal, it shouldn't be a problem, but I'm not 100% sure.
