Would latency really effect this? Ignore the virtual capo part, if you using it as a whammy bar, do we do so whilst picking? It's when you do stuff with a prominent attack, like a choppy riff that I really notice latency. But I don't do that when grabbing the bar, I'm bending something already ringing.
Who knows? I won't be getting one either way, not until it looks like it belongs and also comes down in price.
