I currently own an original L1 Model 1 system and am thinking about upgrading to the Model 2 with Tonematch mixer. Can you tell me when the next generation is due to be released? I've had to live with my 'early adopter' Model 1 while my band mate has enjoyed a Model 2 bought 1 year after mine (it was unavailable when I bought the original). I want to make sure it doesn't happen to me again! Thanks for any input on this.
