It's frustrating for me, too, since, there's rarely been "sequel" compilations. Companies either don't do a follow up collection, and when they do, it stops at the second volume, then "reboot" with a new collection a few years later with the same games. The only ones I can think of at the top of my head that exceeded 2 volumes were the Namco Museum and Midway Arcade Treasures collections.
As for new Mega Man games, I just wish they released another traditional one in the style of the classic or X series. At this point, I don't care if it's yet another series set a bizillion years ahead of the previous series, since they love doing that. Call it Wily & Light: Ambition's Resurrection?!, or some other absurd title while they're at it.
I heard spaceshit noises.
