Whee, a fun and official answer to the question! Yes, there will be a dating game again! It will be run much the same, only there will be a Divider between the contestants and it will be even more fun! And longer!
And we even -hope- to not have it run against Karaoke again! ^______^;;;
Also, no, sadly, we did not invent the Anime Dating Game. I think the general format was prettymuch ganked from what COO (Custodians of Otakudom) have been doing at Sakura Con for years, and I don't even know if they were the first to convert such an event for the anime fandom, though they may well have been...
But, anyway, come! Come in cosplay, even! It's lots of fun!
