I’m not quite sure why everyone is saying that the last really good chance for Porky is this year at TGA. I mean, ya, 30th anniversary and year of the pig (and the sooner we get him the better), but why does it NEED to be this year? The only newcomer reveal I can remember that took place on an anniversary for their series was Little Mac.
In other words, I don’t think it really matters much if he’s not released this year. Sure it would make sense, but it rarely ever happens with Smash. Smash just reveals characters whenever the heck they feel like it for the most part. So, if he’s not at TGA or in some last minute end of the year Direct, I wouldn’t worry too much. All it really takes is them to say “Oh ya, we’re adding Porky in the game as a fighter.” (Which could then optionally be followed by...) “Oh and here’s an EarthBound trilogy too. Have fun.”
