I'm very happy they made Iron Maiden with the layout they did as many people wanted something other than the "same old layout". This puts variety into the hobby and that's never a bad thing. That being said, I've owned MET pro for about 9 months now and still play it very often. I love the layout and the code is excellent. Still to this day I find myself chipping closer to End of the Line, but still no where near getting there. I'll never say anything is bolted to the ground, because things change, but I don't see MET leaving anytime soon. Iron Maiden looks top notch though and I can't wait to play one, to see for myself.

Edit: Also after watching the stream last night I do think Iron Maiden has put the new style LCD to the best use, but I rarely have time to look at that screen when playing.
