I been using L6 products for 10+ years { live and studio } I started with a flextone II plus { for live } i purchased a xt pod and a xt pod pro about 4 years ago { i use the pro into a mesa/marshall rig live now }  I'm toying with the idea of a X3- I was amazed to see that line 6 don't make it anymore { thats the scary part- Reminds me of microsoft comming out with a new os every 2 years } As i'm comparing the new HD to the X3- I think i want the x3-- I don't see the difference between the 2.. I wonder if the HD will be obsolete next year? Whats next ??  For now i'm sticking with my flawless xt pro rig.. I really was dissapointed to see theres no support for the x3 on their site..
