It's not clear if they meant the 5-pin cable or USB for comparision. Most
latency comes from the analog to digital and then digital to analog conversion anyway and the processing of samples in-between, and since there won't be any module sounds, just a plugin, things could just fail on the users' crappy computers, no matter what, like in most cases today. I find that a bit risky to hang their reputation on some software running on messed up crashy Windows laptops and then listen to people with their broken drivers and blue screens after selling a kit for who knows how many thousands of dollars. I hope the trigger interface box will be at least class compliant and not rely on special apps to work.
I would be surprised if Roland wouldn't use this new wireless technology for their own kits after a while...Although in many cases plugging the wires in once is less hassle than changing dozens of AA batteries. Or future problems like "dam, I forgot to put the china on the charger"...
They should add solar panels to cymbals.
