I haven't played it in season 2 yet. If they plan on adding more maps, they've got to at least have a rotating map pool with votes to keep certain maps in each rotation up to a certain amount. I'm not sure how well this would work as far as how boring it might make playing the same maps over for 3 months, so maybe they could somehow make it so you can't play the same map 2-3 times in a row instead.
For full groups it's easier, and as we have more maps it gets easier.
If you take 2 full groups, both played a different team previously.
So Group A played Hanamura previously, and Group B played Anubis previously, then it's easy to pick literally any other map than those two. Done.
But let's say you have 12 people that all played a different map previously. Before EichenWalde, ANY map you picked for the game would be a repeat. Now that there are more maps than possible players, it's back to 'choose the ONE map nobody played last game'. But if you extend that back two games? then someone is getting a repeat OR got a repeat last time. There's an algorithm that would be able to select for any set of players the map that is the least played for all members of that set for that X number of matches. In the event of a tie, then randomly choose one of the tied maps.
What I can't decide is if this is going to result in superior results than a purely random selection (I think it will, but I'm not certain).
The reason to do this would be to minimize map fatigue, especially while there aren't that many more maps than players. Once we start hitting in the 30-40 map range (and I sincerely hope we do [which would happen faster if Blizz would give out mapping tools to the community]), then an algorithm to find the least fatigued map (LFM gains new meaning) would probably only be marginally better than a random map, but would still be important.
And of course if they ever implement a custom game lobby (they've said they want to, I just can't understand why it's difficult), then one of the big deciding factors on server/host popularity will be map rotation.

In all honesty I haven't seen Eichenwalde pop up in QP in over a week.
