Excuse me for asking, but did you read the note next to Sonic X!Sonic's age? It was elaborated very clearly on how Sonic would have aged. Saying that Sonic had not aged during these time-skips would be the same as saying that Chris does not age, and he did.
I admit it is unique situation. I am just paying respect to the fact that time moves in Sonic X. If Chris aged during the timeskips, it would be logical to assume that Sonic has aged as well. I have further examined Sonic's Eyecatch card during the Metarex Saga, and they mention nothing of his age being 15.
And now, Ultrasonic, you know why I started this kind of conversation to not fall off the wrong side of the bed. Not like I would deserve the praise like this, but... I considered that this is safe way to make a big change. Sure, typo and little mistake, I can fix that without need your approval, but for a big change, like Wispon Description and stuffs at that scale... it required some talks and discussion before I can go ahead and change them.
As of the old saying; "Think before Action." - that advice usually works.
Look, the game makes very explicit that Classic Sonic hailed from an alternate dimension, and the true ending for Sonic Mania, which was confirmed by the guy who does Sonic games to be a direct tie-in to Sonic Forces, shows Sonic AND the Phantom Ruby being sucked into a wormhole created by the latter. That's about as explicit of confirmation as one can get and is not speculation at all (at most, it's more "putting two-and-two together" and "inferences"). So no, it's not speculation. Is it an indirect statement? Possibly, but it most certainly isn't speculation by any means.
I assume the reason why you undid my edit is because you believe that its not confirmed considering it could be the frenzy wisp. I'm positive its the void wisp from DS Colours. Every wispon shown thus far resembles the original wisp. Burst wisp: the gadget from the front view is the same shape as the wisp and the 3 tri-angled holes represent its three eyes in its respective position. Same thing with the lightning, drill and cube wispon. By that logic, the void wisp is there. As you can see in the box art, from the front facing view, its circular like the head of the void wisp. The little sticks attached on the head represent the fuzzy ridges of the wisp's head. If it was to be the Frenzy wisp, I'm 100% positive that it would've be shaped more like the 2-horned head it has.
However if I am wrong about your thinking and it was simply because Sega themselves haven't officially confirmed it, I understand and I apologize. I just felt that the Wispon's wisp was obvious enough.
