i'm confused by the thread title. I have yet to see a single announcement that states DMC5 is a reboot. I believe the proper term for a game appearing earlier chronologically in an established continuity is "prequel".
I kinda like this article personally, though even its writer refers to it as "rebooting", and honestly until I see an official announcement from Capcom that this game is somehow completely re-establishing canon, its not a reboot as far as I'm concerned. DMC's continuity has always zigzagged, so seriously what's the big deal?
Also, the trailer is totally badass, and Dante, despite believable stylistic changes, is totally badass, so seriously what's the deal with everybody heaving dramatic sighs and declaring RUINED FOREVAR from 2 minutes of teaser trailer?
