Are all Shimano groupsets sold with H2 bbs?

Do all Shimano groupsets come with Hollowtech 2 bottom brackets? Whenever I see these on sale the only choice seems to be an English or Italian thread, but there never seems to be an option for BB90, BB30 etc.

Does this mean there are a lot of unused H2 BBs out there?
