Well, I got MM#55 in my mailbox today, along with a letter from Archie confirming that it is, "the last issue of this series." Any remaining Mega Man issues due in subscriptions are getting transferred to Sonic Universe (unless you contact Archie to request a different comic).
I believe the previews dropped this info already, but the issue is essentially Dr. Light experiencing a series of visions, so you can basically call this Rock of Ages 2. It's triggered by his working on the Time Skimmer. Each game/series/event is given a full page art piece.
[spoiler=Summary]We start with MM4, then jump to a Quint/Killers/Wily Tower page, then 5, then Stardroids, then the expected 6, 7, 8, 8.5, 9, and 10. Of particular note is that Light does recognize his own robots in the MM9 page, but does not appear to be aware of their expiration dates. Tango appears on the MM10 page for some reason, on Blues's shoulder.
Next page confirms the Time Skimmer is THAT Time Skimmer. Wily shakes hands with his future self, Mega Man is turned into Quint. It seems Archie subscribes to the notion that Rock can't escape that little predestined paradox. Two small panels at the bottom of this page show the creations of X and Zero (Zero's face is hidden by Wily's shadow, but the booblights are plain as day).
Nothing on Rockman Shadow.
Next up is a page for the X series. The design choices are, interestingly, the inverse of Zero's Tatsunoko Vs. Capcom ending, in that X, Zero, and Axl are sporting X8 designs, but Alia is not. Page also features Cain, Sigma (X5 version), Iris, Colonel, Signas, Douglas, Lifesaver, Layer, and Palette.
No Command Mission. D'OH!
Next up is another series-gap page, and this one is all Elf Wars. X and Zero, along with Axl and a Cyber Elf Dr. Light, are battling against Omega and a couple of Golems. Dark Elf and the "middle aged" Weil (unused design from MMZOCW) are seen in the distance.
Next is the expected MMZ montage. Zero, Ciel, the Resistance, Neige, Craft, the Big Four, and both X's. Weil and Omega do not re-appear.
ZX page features the Sage Trinity, Prometheus, Pandora, Giro, Prairie, 8 Biometal fragments (Model O and the Core version of Model W are both absent) and all four protagonists in Hu/Re form. Despite this, Vent and Aile (pre-Advent designs, if you're wondering) are sporting the X Buster and ZX Saber.
Legends page, Volnutt, Roll, Barrel, Data, and Bonnes. This one was in the previews also, but if you missed it, Tron is piloting an open-cockpit version of the L2 hover-Gustaff.
When Light comes to, he does momentarily ask himself the age-old joke-question of whether or not he's doomed humanity, but he quickly dismisses it, resolving that while there will always be adversity and people who abuse his work, there will also always be hope, and a Mega Man to protect the people.[/spoiler]
In the back of the comic is two letters from editors, a generous portion of fanart, and a full page "Short Circuits" strip which features an insanely large abundance of Mega Men (including but not limited to four different "bad box art" variants).
