I really can't tell what they would do because they are unpredictable. But here are possibilities:
Recording:
Studio time and writing (Mike is already writing)
That could lead to an EP/LP
Possible acoustic sessions? It would be a rest for Chester
Live:
Who knows what to expect, this isn't as bad as when a musician enters rehab but there's no way that the entire tour would restart. Maybe most of the shows that they cancelled. They have more time for rehearsals now but will they use that?
Side projects:
Mike might not do anything with Fort Minor but we will get something from him in some way, maybe he will collab with another artist or group, he is very into that now. Hell, maybe even Brad or Rob will lend their talents to some other artist's material, Brad has become good at programming, producing, and finally guitar.
Still counting on stuff from LP because they said that this would be an LP Heavy year
