- The "stage hazard" Ridley they showed was suspiciously small
- They tend to kill false speculation based on something they've said/done as quickly as possible, they aren't likely to be unaware of this 1.5 million view hyper thread on Ridley, yet here we are literally a year later with them not killing off speculation about him being playable based on what they gave us
- They've listened to requests on characters for this game, including megaman, they are unlikely to have ignored the the desire for Ridley
- They've clearing hyping something, and leaving it late to reveal, do you really think that one of their big final reveals, so close to release, is going to be a stage hazard?
If you're losing confidence, that is exactly what they want. Regardless of if he's "in" or not, they're building something up in this regard. If he is a stage hazard, he better be the best damn stage hazard the world has ever known, or they may have a PR disaster so close to release.
