Honestly, I don't think we will.
"Peak" Federer had an all court attacking style that combined Sampras with the baseline hitting of someone like Agassi (sort of) or Lendl - but more elegant. It's the kind of thing you design in a video game. Fluid big serve, S&V style, but comfortably hit from the baseline, too, and all day. Defense is good, but also loves to attack. Seriously, I've watched tennis since wooden racquets were still around and I've never seen anything like it in one player. I could be wrong, I'm more than open to suggestions.
But, the courts have slowed down. Federer grew up in more varied surfaces, faster grass, maybe different hard courts. That's not to say those things were in effect during his peak, but as a young player, coming up through the juniors and ranks during his development during the 90's. String technology was just developing polys during that decade and racquets still tended to be pretty stiff and heavy.
Nowadays, with the courts and surface homogeneity, string technology, and lighter racquets - no one teaches those things like they did back then. Eastern forehands aren't very common. Volleying is a bit of a lost art. Most of the youngsters play the same, frankly. Meddy with his flat-ish vaguely Connors-esque strokes is an outlier. Shapovalov has the trappings of it, but he's pretty inconsistent and his net game, while decent relatively to his peers, wouldn't have rated at all if he was in the 80's or 90's. There's a few others, Hurkacz and Humbert, but ... yeah, not really.
What we mostly have is a bunch of pseudo-Djokovic-esque clones. They're not as varied, as tactical, or as well rounded as Novak, though.
So, no we won't see that again in terms of style and level (of that style).
