I personally think that although Incredible Hulk looks like a great coaster, B&M are going to stick with their tradition lift hill ways.
I would say leave the launched coasters to Intamin, because soon most coasters are going to be launched (at least that's what I think), so it would be nice to have 1 line of quality coasters to always have a lift. It just seems like it's better that way.
I actually don't know what they're going to do. They're coasters are always going to be great, launched or not, so go ahead and do whatever you want B&M.
This post was more of an opinion, and my opinion is that they should stay with lifts.
