I didn't think so myself. To me, a "good" / classy park with high attendance getting a B&M almost seems a rite of passage.Efteling getting a B&M dive coaster. Seems part of the furniture now but at the time it was announced it was really shocking!
Though on that topic, Holiday World getting a B&M wing considering most of their other mechanical rides seem cheaper.
As for the topic, I sort of felt that way about Energylandia initially when they were building AAA rides in close sucession. I mean nothing would shock me now so if they get a Giga or something it'll be totally be normal.
