if you ask these other guys on this forum who bought early gen Axe-FX, they are still getting updates and support until now. So, no, Fractal never leave their customers. who do you think they are, Line 6? the worst company ever when it comes to costumer support. they just abandon all their line of effects unit/ processor. just look at the hd 300 to 500x, that was not so long ago (2010) that it was released, yet no more update or support. The Fractal's first version, called simply Axe-Fx, was introduced in 2006 and until now people still get help and support and updates. goes to show you that fractal love's their users/community and their dedication to their product is superior to any other companies out there. That's why fractal will always be on the very top of the Effects Processor Units. and why almost all bands and artists will keep using them.
just my two cents!
