Usage notes
Linguists had remarked on the lack of "hopeably" by the late 19th century. See, for example,

It was proposed as a "proper" alternative to hopefully in the sense of "it is to be hoped", by analogy with "regretfully" and "regrettably". (See, by the same author as the 1975 citation, and the Coale citation above.) It has not caught on, perhaps because "regrettable" exists and "hopeable" does not.

It seems to have gained currency among Sikhs in India. The 2000 citation above is one of many.
