...This wait for information is killing me. The website is mostly just filler with short blurbs on existing fighters plus videos that are already on the site and which most of us have seen already, and as the days and weeks drag on, the chances of something happening to either deconfirm Lip or hurt her chances severely just keeps going up. Even though we're in a better place right now than we ever were back in the SSB4 days, this is already my least favorite Smash speculation period.
I understand that pain about waiting for "new" information, I was honestly expecting some sort of update for the release of the Captain Toad ports (whether it be music, a stage, or an Assist Trophy), and there was not even an acknowledgement.
My current theory as to when we will finally receive new information is during whenever they decide to confirm the next newcomer (which might be during the weeks that WarioWare Gold releases). Many people, including myself, believe Ashley will be confirmed at this time.
As to this being the "worst" speculation period. Nah. During much of pre-Brawl, we were not receiving new information at all, and the Dojo did not start until May 22, 2007, and it was not until August that we actually saw a newcomer after the E3 2006 unveil (which was in May of the previous year).
Even with Smash 4, we did not see our next newcomer until six months after the E3 2013 unveil (Rosalina in December).
Ultimate has the shortest speculation period since Smash 64 to Melee. We only have five months left. Be thankful that you still have time to hope, dream, and speculate for this round. That is a privilege that that many other long running fanbases do not have (Bomberman, Takmaru, Sukapon, Samurai Goroh, Krystal, Lyn, Tingle, Stary, and Waluigi to name some).
Lip has survived thus far. Appreciate that, unless you are someone that just wants it "to be over with" which I can understand as well (I can sympathize on this front as well, I really wanted to Sakurai to outright confirm that Ridley was a stage hazard boss after the April 2014 Smash Direct since so many idiots believed that Sakurai was only playing "mind games").
We shall see what ultimately happens with Lip and Panel de Pon content in general. However, keep in mind that you are not alone. Isaac fans have traditionally had to wait until a game's release to not only figure out what Isaac's role in each game was, but also what content Golden Sun even had in the game.
There are five months left. Let us appreciate this calm for now. It may be for only last a few more weeks, or maybe even another month or two. Regardless, just continue to hope, dream, and discuss what you appreciate and enjoy about Panel de Pon.
