I wish I still played portables so I could jump on Black/White 2, but as I've gotten older my downtime during commutes and such don't really warrant anything more than some cheap iOS games. My DS Lite hasn't seen any action since Soul Silver. :/
Darksiders II for $16 is still pretty good, though. Think I'll grab the first one, too. Seems like a good time to do so since they'll probably go out of print in the near future.
