Fashion is cyclical, so, sooner or later, practically all trends come back around, to varying effects.

That said, all sorts of design movements in different directions are always happening simultaneously in fashion. Trends just represent the few specific styles that many designers are coincidentally expressing at the same time, hence, they stand out. These trends become more popular and trickle down to the public (late adopters) if enough fashion forward people like them.

When trends come appear in any given context, they are usually influenced by the current environmental factors (technological, social, political, economic, etc). For this reason, we may see more elaborate styles in men's dressing in future, but never to the extent of previous eras alluded to in the question details, because the lifestyles people led then were completely different. E.g. the costume of an 17th century aristocrat as shown below was highly elaborate yet completely practical for him, because he didn't have to do anything: He didn't have to work or otherwise exert himself. He maintained a retinue of servants and didn't even have to groom or dress himself as his valet(s) took care of that, which made living in such costumes easy. In contrast, this outfit would be highly impractical, even for a wealthy man in today's highly mobile world. Somehow, dashing to meetings or parties (even if via private jet or limo) in such an outfit daily would just not work.
