I don't think we have a reason to assume either Grateful or Mugen will be web exclusive right now. One or the other may be, but so far this is just the fourth retail release in the Ghost line. Necrom will probably be a fifth, but there should be at least 2 more figures after that (hopefully; both Gaim and Drive had 7 retail Figuarts). So say we have 2 left, what are they gonna do, Deep Specter and the Machine Hoodie? It seems more likely to me that we may finally see all 4 of the main Rider's main forms released this year.

Or at least I can hope.

In any case, I like Boost more than Grateful, and honestly considering Boost has pretty much completely taken over the "default form" role for Takeru at this point in the show, I would have been bummed if it was web exclusive. Definitely a more relevant form than the past couple of early upgrades.

edit: though...are we sure he's a retail release? The price listed is exactly the same as the web exclusive Musashi, about 1000 yen more expensive than Ghost and Specter. Why would he cost so much...? Hm...starting to worry now.
