Thanks for the response however I have to disagree. If there is one thing I've learned in 30 years of making music AND developing technology its that scalability should always be a consideration. All 4 boards will serve my needs today so future support and scalability is important. I've owned and continue to own numerous Line 6 products Variax JTV-59, PodXT, Amplifi FX100, Stagesource L2t / L2m and have always been impressed with the quality of the product. However, the long delay in shipping combined with the comments about slow / no release updates and communication are making me wonder if Line 6 is planning on making a major product shift away from the M20D. Having once worked for Apple they would exhibit a similar behavior when sunsetting products.
