Probably until they run into firmware space and processing power limitations. Most likely is that for quite a while you will only see Axe-Fx 3 updates, depends if there are dedicated firmware programmers for handling the Axe-Fx 2/AX8 updating. If you have a 2 or are planning to buy one then just get it and enjoy it. It sounds fantastic at the moment. It really doesn't matter if the next gen product sounds even better in a year, the 2 will keep sounding just as great as it does today.
