@DeadParrot and how long they'll go without Cutie Marks.
I get the feeling that if they ration their material they can use for ACTUAL crusading, they might get about 4 or 5 more CMC Episodes before it'll start feeling like they need to get their cutie mark.
…Which should last us another Season or two.
And considering my theory that the show is going to have a kind of "Shift" sooner or later, that may be a nice point to bring it up.
…Although that may be semi wish-full thinking. I like how the show is now, but I can't help but entertain the thought that there will eventually be a more Arc style Quest season(s). I mean, a season where the Mane 6 journey across Equestria to solve some large problem, and they help out others along the way?
I may have my head stuck in traditional fantasy stories too long, but that sounds cool.
…I think my brain switched tracks in there somewhere… Sorry about that. I need to have a word with my Brain's DJ.
Edit: Oh dear, others posted while I was typing.

Okay, The CMC may not get to go Crusading at some point, but that doesn't mean they disappear.
I can Imagine that the three would probably spend time working together with their specific talents. Towards some other lofty goals they may end up with. Their skills do happen to be things that can do shows like what they first tried right?
So they may become a group of traveling performers, which would occasionally show up in places like Manehatten trying to get notoriety for a big event like "Battle of the Bands".
…And possibly, they may end up getting in a few bits of trouble. Whether it be some hair-brained scheme to get attention go wrong, or they get mixed up in something they don't belong in.
And hey, if my "Pony Adventure" wish gets granted, they may become adventures themselves; going around solving problems… in a manner that would befit Scooby Doo's Gang.
…Also, if one of them get a cutie mark, and the others don't, it will probably lead to simply more episodes as they become desperate to find the other two. The one that gets the mark first is going to simply be the one that becomes "De-facto leader" being "Thou wise one who hast come before", and will probably end up coming up with most of the plans from then on… only for most of those plans to still wind up ending horribly.
