I checked the Line 6website yesteday and it wasn't listed. I was trying to find out when the Liqua-Flange was going to hit the streets. I called today and was told that they are starting to ship in one week. Hopefully in time for the three day holiday weekend, so I can sit back and play. $119 for the Rotomachine is a steal!
One thing about the Boss that I think may be a misunderstanding -- I've heard a few people on the various boards refer to a "B3 sample" in the pedal. If you watch the Boss demo, the guy quickly refers to the "organ sound of my GR20" guitar synth. In other words, that organ sample is in the GR20, not the RT20 pedal itself.
Definitely interested in a shootout between the Boss, Line6 and DLS, though!
