I am in favor of separating the large fact tables into their own filegroups - based on better data and analysis.
I don't necessarily think that the fact tables should each have their own filegroup. But if you can split out the fact tables into some configuration of new filegroups - it would prove beneficial.
Where is the benefit of doing that?
With data this size, it provides a more robust opportunity for recovery. Sure you can see some performance gain (whether on same disks or not). But the big benefit is being able to take a filegroup backup and restore a filegroup backup (when/if necessary).
Maybe somebody wants/needs a 2TB group of tables restored to a dev or qa environment. With FG backups, you can achieve that without having to concoct a process to move the tables via bcp or ssis, or worse via backup/restore of the entire 50TB database.
For anyone interested in such a process, it's called a "Piecemeal" restore in Books Online and such restores can frequently be done online with little or no interruption in service.

Although they tell us that they want it real bad, our primary goal is to ensure that we dont actually give it to them that way.
Although change is inevitable, change for the better is usually not.
