I have been using Line 6 since the first red bean - I remember getting excited when the update CHIP came out... I have been faithful to the brand ever since. That said - we are getting too used to the iOS/Android app and hardware model with perpetual updates to 99 cent apps - in fact, my original Angry Birds just updated today - how long has that been around????
I finally traded up from my X3 Live to the Firehawk and am absolutely astounded at the improvements and the quality of the delays and reverbs - the touch of and air around the HD amp models is amazing. I cannot wait to plug into the board at church next weekend and hear the new ambient pads I can do with this thing. I am looking forward to using this for years - whether it gets updated again or not.
All that to say... I do think that Apple/Android model should be considered a for a minute with the new devices and with the evolving expectations of the user community. Considering that the processing power is so high and the hardware is really heavy duty - it is almost a waste to not run the life cycle out a bit longer. I would eagerly fork over good cash to download and install new models and features to this device - like I can in AmpliTube and JamUp on my iPad. IMHO - this is the ideal size, shape, and layout (tho I would prefer the FX ON/OFF) - and I REALLY like the ability to edit from my iPad or phone. I have had a few connection issues -- and just rebooted the iPad and it has worked fine - inconvenient - but way better than the X3 with the cryptic menus and forgetting that I was on the top row and not the second row when turning the knobs.
So I guess your perspective and expectations of the Firehawk may also be shaped by where you came from to get to where you are now. New features would be cool though! :-)
