I wouldn't be surprised, there's La Ronde with their 2 Inverted roller coasters, along with Six Flags Great America having two wild mice. But the sad thing is, the last 2 roller coasters Great America added were wild mice, so at least New England is getting a major addition since what... Pandemonium?
Six Flags New England's just recently had a new addition and it is... a Wild Mouse. I can see La Ronde having two inverts, but Flashback and Deja vu have the same layout... it just seems pretty strange to me and I think some of the gp will notice because the two rides wil be so close togather
