I know that I don't really have any say in this, but I feel like if I were running the gathering, I'd prefer it to be more inclusive rather than exclusive...so if a case can be made that a character or series fits, then I'd rather include people who are potentially old school fans even if it can be a bit fuzzy.
I've also seen the gathering in past years say that as long as the character existed before the cutoff date, then it's fine, regardless of outfit or anything like that. I suppose an argument could be made for the same about the series itself, or for one or the other to have existed.
(I know that I personally have done SEVERAL cosplays that originated in 1999, which I think has been used as the cutoff year in previous years of this gathering. Why is 1999 such a good year for cosplay for me? lol)
Either way, excited for the gathering. 
I know for at least the previous two years it has been anything pre-2001 and that's the template I want to follow. The crux of the gathering is really to have a generalized place specifically for older series fandoms that otherwise wouldn't have enough singular pull to have individual gatherings. Also a place for people to get out there and see what they've missed because we've all missed so much!
I would also like to keep it Japanese based, which I do recall was a request in years previous as well. However if someone shows up as, I don't know, Dilbert for a random example, they won't be turned away or anything. It's a request, not an enforcement as I'd like to think I'm not
that big of an ass.

So yeah, it's exactly what is described in the gathering introduction - "
Essentially if your cosplay character appears in Anime, Manga, Video Games or Live Action pre-2001 on back, then this is the gathering for you!"
If they were created before 2001, you are good to go!
