The footage above isn't from the Luna version, FYI. Early impressions suggest that the game runs as well as its console/PC counterparts. Barring a decent internet connection, it sounds promising.
With 1.4 million units under its belt, Mega Man 11 is on its way to becoming one of the franchise's best selling titles. The jump to Amazon Luna only furthers Capcom's evergreen strategy, which aims to maximize Mega Man 11's audience and profitability. This approach has proven successful enough; seemingly replacing the franchise's reliance on a yearly "core" entry to retain profit.
A brand-new, "major" Mega Man title is expected to launch between Q3-Q4 2022.
