Plus they have a lot to loose if it comes out of the gate with issues. A lot. They are about to break into a market with a pricepoint that opens them up to line 6 type buyers. failure here could doom them in that market, but i suspect it will be a glorious success. I like a company that delays a product to get it right, and spends the right time on QA and beta testing. To me that has more value that getting it out fast. Ya'll have been playing guitar without the AX8, you will make it til it comes out...
Also note, even when it comes out, you likely are still waiting even longer. Just chill out and rock out with what you have.
