Justice League United and the Infinite Man?

According to the Nerdist, the Legion of Super-Heroes returns to the DC Universe via Justice League United Annual #1.

The solicitation copy says:

"The Infinitus Saga begins as the Legion of Super-Heroes arrive with the shocking news that the 31st century has been destroyed! Now it’s up to the Justice League United to save the future!"

What catches my eye is the mention of Infinitus. I'm not that up to date on the Justice League, but I didn't catch any mention of Infinitus yet.

As a long time Legion fan, however, the name Infinitus calls up memories of Professor Jaxxon Rugarth, a poor, doomed volunteer for one of Brainiac 5's experiments (well, Rond Vidar was also primarily involved in its origination and conception), also known as The Infinite Man!

The Infinite Man was born from the exploration of time, and testing its cyclical nature. Unfortunately, Prof. Rugarth discovered that time was cyclical (something that the Time Trapper would certainly take issue with) -- an infinite cycle! Rugarth gained immeasurable power from that infinite cycle of death and rebirth, and became a creature with control over time and faced off against the Legion!

I can't remember where I encountered this story first; memory tells me I read it in one of the digests that made its way to Philippine shores, or perhaps it was one of the 'bootleg' copies reprinted by National Bookstore (legal at the time, I think, due to some loophole governing intellectual property) that I read at the barber shop.

Later on, the Infinite Man would indeed face off against the Time Trapper as personifications of two theories of time.

And it was also revealed that the existence of the Infinite Man shielded the 30th Century future from the ravages of the Crisis for a time. But when the Infinite Man lost his abilities (and left Rugarth a comatose vegetable), they were suddenly vulnerable to sudden shifts in reality with time being more mutable now.

I think it's significant that hypertime is mentioned this early on in the history of the Legion -- perhaps it's what spurred Morrison on to come up with his own theory of hypertime.

Well, we'll see what Justice League United shares with us about the future to come, won't we?
