I think the correct and most honest is: we don't know.

Profit-switching mining is still relatively young, so it's hard to look at the last month or two and interpret that as a trajectory of future profits, that's one problem.

Another problem is that Bitcoin took a hit within the last three or four months, and when Bitcoin takes a hit the whole cryptocurrency market goes with it.

Also, there's more profit-switching pools popping up, and more people hopping on and mining.

I don't think having a linear perspective on profit-switching mining will yield accurate predictions. We could just be in a lull for now and the people wanting a quick-buck will leave; or it could be more permanent and profits will go down while altcoins will grow resistant to multicoin pools. No one knows really.

That's my $0.02.
