The timing suggests a potential "it's out right now" was delayed.

A taste of the Blue Bomber's newest adventure is now on the eShop, and only recently appeared.
Mega Man 11, in addition to being available for pre-purchase on the eShop now, also has a demo available for download. The demo has one stage - Block Man - but multiple difficulty levels.
The demo went live at approximately 7 p.m. Eastern time, suggesting it was due to launch after the delayed Nintendo Direct.
