BT and Wifi support require hardware. IDK if the 9-10 year old Helix has either of those components, as they were not as prevalent way back when the Helix first came out. They can do a lot with software but the hardware is set in stone until they make changes for the "H2". So, if the Helix doesn't have Wifi or Blu Tooth now, it's not going to until a new hardware unit comes out.
I've been toying with the idea of getting one. I've had the PODHD500X for a few years now, and I really have no need to replace it other than G A S, so my concern is dropping almost $2k on something that will be replaced/replaceable within a year. It's the catch 22. Do I buy a piece of 10 year old tech, know what market trends are? Or do I keep stalling out for another 12-18 months, just to find out that I should have just went ahead and pulled the trigger when I originally wanted to because it didn't get/isn't getting replaced? (IDK about isn't. Eventually they are going to release a new flagship pedal board type system.)
It's happened to me so many times where I bought a piece of gear and the new version comes out within 6 months - 1 year. Sometimes even less. Like when I bought an Oxygen keyboard just before they re-released them with drum pads. Had I known M-Audio were releasing an updated version, I would have waited 3 months to get that instead, but I got stuck with it because it was just barely too old to return/exchange.
That was like $130 and it hurt. I don't want to have that same experience with a $2k piece of gear.
