I don’t think they are going to cover 4 specifically more than they already have. At least not until they finish the SF3 arc at best. They didn’t go to deep into it because the game was making the rounds, and ultimately the goal is for you to play the SF4 game/games to see what happens.
As for the new comic, from the press release it seems like they are going to build up to the SF3 Tournament. Since they mention Gill’s organization specifically and not, whoever they are fighting in 5 (I don’t think it’s Shadaloo, since Master Bison and Claw are not final bosses). I suppose they could mean the new SF5 game as the new tourney, but they will probably hold off for the same reason they didn’t tackle the SF4 tourney when the game was making the rounds.
***"Street Fighter™ comics are back with STREET FIGHTER™ UNLIMITED , an all-new monthly comic series arriving in comic shops December 2015! Street Fighter™ Unlimited combines fighters from all eras of Street Fighter’s nearly 30-year history in a Canon Spiking, Sonic Booming, Hadoken-throwing martial arts melee!
The new monthly series will be helmed by returning Street Fighter scribe Ken Siu-chong (Street Fighter™ IV, Super Street Fighter™), while pencillers Joe Ng (Street Fighter™ Origins: Akuma) and Edwin Huang (Skullkickers) will trade off art chores tackling 4-issue story arcs. The story promises to be UDON’s most epic yet as fan favorites Ryu, Chun-li, Guile, Ken, Alex, Cammy clash with not only the villainous Shadaloo organization, but also the invincible Gill and his cult-like Secret Society. It’s all leading up to a new Street Fighter Tournament featuring more World Warriors than ever before!"
We still don’t know if SF5 happens before the SF3 series or after. Either way, maybe the comic will tackle stuff from the new game. At least age Master Bison and get Cammy out of that dumb Delta Blue unit (really, WHAT THE…), but who knows.
Mega Man #53 was AMAZING!

[details=Spoiler]Wow! The robot museum mentioned in the Gameboy games! Guess this world will go a different path since the original 6 robots don’t wind up there, but who knows. Well Enker and a new Skull Castle with Wily can cover most of the important stuff in the first game anyway ha ha!
Mr. X’s reveal, OH SNAP! Very clever. Didn’t see that one coming!
It’s too bad that it doesn’t seem like the writer Ian Flynn will cover 4 completely and you have to rely on the game to see what happens. But after covering 1, Powered Up, 2, the Wily Wars, the Japanese only PC game and 3 well guess he can skip over one.
I kind of hope it isn’t being skipped because of the hiatus though. Well hey maybe next issue - Red Shift - will tackle the part where Break Man becomes Proto Man.
Crazy props for using Break Man THIS LONG! That’s amazing.

I’m sure going to miss this book during the hiatus. 
Picked up the Devil May Cry art book but not going to tear into it until I get home! LET’S ROCK BABY! B)
