I wouldn't be surprised if the layout is done by the end of the month. Testing starts a few weeks after that, maybe sooner.
Honestly I'm not a big fan of these family B&M's we're seeing installed because they seem like big bulky overkill for the basic layout they're circuiting during the ride. And B&M tends to juuuust undercut ride expectations compared to the actual experience (there are exceptions, of course).
It's not going to be getting *me* out to the park for a revisit, but this one DOES look quite promising and I've heard pretty good things about the stand up they installed (minus a comfort issue with the restraints, I am not a fan of those collar restraints either). This looks like it will be perfect for the kids who are intimidated by say Mantis or Kraken, but are building up their confidence to the big boy coasters.
