Okay, now that I could sleep over this all, I did some thinking on the situation of X and Elma for Smash. This Direct, like pretty much all the past ones, have all been exclusively focussing on games that come out over the next couple of months. So really, after this Direct, we can only say for certain that an X port won't come until February next year, March at latest. With the remake coming, they also have to know that people are going to ask for X all the more. They just can't be ignorant on it. So my guess is that they didn't want the remake stealing its attention (or it stealing the attention for Daemon X Machina or TMS#FE), and might just announce it at a later date.
Also, like I mentioned last night: It's really odd to me Terry is already coming in November. That's what really gets me wondering about when they intend to reveal and release the 5th fighter. And now that it's revealed that more fighters are coming, I'm honestly starting to feel like it would be far less of a big deal if the Fighter's Pass wasn't all third-party. So yeah, the wind blows hard in December, I guess.
