Regardless of where the rumor comes from, I can certainly believe that supplies may show up this month, and certainly going into June. Sometimes they deliver steel early anyway, like how Maverick sat in an open lot outside Cedar Point for months before it was even moved into the build area.
I'm not sure how closely the Clermont plant is watched, but last I saw, there were enough different coasters under construction there that some of them were anyone's guess. It'll be interesting to see if track gets spotted on the road again. I remember when Wild Eagle was still a rumor, the first time we knew it was a B&M was when the track actually got spotted heading toward DW before the first delivery was even made.
