I somehow doubt that, what with the fact that Magic Mountain currently has a coaster under construction and all.
Granted, back in 2000 they had 3 coasters under construction at the same time, but they were all announced at once.
My guess is still on the Alton secret weapon coaster. But that's just because we don't know where this track is going, whereas we don't know what kind of coaster alton's getting, so it's just connect-the-dots.
I would like to think that Alton is getting something a bit more interesting than another B&M. Even if the ones they do have are great. Simply because Alton Towers is the british version of the old Coney Island - in terms of being a hotbed for rollercoaster prototypes and advances.
Trust me, it WONT be for Alton, or any other British or European park.
Like I stated the other day, as far as I'm aware, all European B&M's except for Dragon Kahn were manufactured in switzerland, including Blivvy, Air and nemesis.
