What refurbs would be moved earlier because of the 60th D.A. celebration?

I know that some refurbs like late summer HM are pretty much clockwork, but now with the May 22 opening for the 60th Diamond celebration; do you think some of the historical refurbs have been moved up from their traditional times? For example, Matterhorn which is predicted to be in August this year.
