With the opening day for Banshee come and gone news has gotten around that Diamondback @ Kings Island, Intimidator @ Carowinds, and Behemoth @ Canada's Wonderland have all had seatbelts added to their trains this year. So far this addition only seems to be affecting the Stadium-style seating trains. The only other B&M Hyper in the Cedar Fair chain is Leviathan, which uses the traditional four across seating and does not have seatbelts as of right now.
The only other B&M Hyper to have seatbelts was Nitro, but those were removed at the end of its first season and have never come back. Steel Dragon 2000, when it got its new B&M trains, also came with seatbelts. Who knows the reason why these were added when the rides have been around for years (2008-2010 they were built), and they have not gotten new trains either. Here's some pictures of Diamondback for proof:
