Here's my two cents:
When Sakurai talked about the new DLC in the Banjo-Kazooie spotlight, he seemed to emphasize the special position Smash Ultimate is in, where this prestigious and ridiculous level of crossover madness has been reached - the levels of which will never be reached again - and so they're going all out with insane character picks from throughout the history of gaming. To prevent myself from getting my hopes up, I'm choosing to believe that his remarks mean that the remainder of this game's DLC will be just as off the wall as the first Fighter Pass has been.
On the flipside, he made sure to emphasize that the future of Smash, post-Ultimate, will feature significantly less worlds colliding with each other. That is where our day in the sun will more than likely be, IMO, because the focus will no longer be on bringing everyone back, or putting in the craziest and least predictable characters ever, but on trimming the fat and bringing the focus back to Nintendo (well, at least putting a bigger spotlight on Nintendo than Ultimate has provided).
I suppose, so long as DLC is made, there is always the slight chance that Ashley will make the cut. But, at this rate, we're more likely to see Gordon Freeman, or The Heavy from TF2, or Cuphead, or Earthworm Jim, or Steve, or Sub-Zero, or any number of completely out-of-left-field choices that I never would have even considered in the running to be a Smash character when I was a wee lad playing Melee with my brother.
As far as today's Smash-related releases, I have finally bought my first two pieces of Ultimate DLC, in the form of Banjo-Kazooie and the Sans Mii Costume. BK is the first and currently only Fighter Pass character to excite me in any way, shape, or form, and Sans...well, I've got a soft spot for memes.
