A whole bunch of new challenges popped up for KI last night, the first of which starts today...

Most of them are not likely related to pins since they only have a time span of about a week each... except for this one:
World Tour Part 2
You defeated 7 Different Characters in Online Matches
starts 8 Feb 14
ends 30 Mar 14
That's a whole month to get it done, just like the On A Roll Challenge... So I would suspect that this one will be a Pin Challenge... and probably considerably easier than On A Roll (it doesn't say ranked so it could be boosted with a friend)
--------
All of the other challenges could be done in off-line mode except for this one:
On a Streak
You won 5 Consecutive Ranked Matches!
starts: 20 Feb 14
ends: 27 Feb 14
Which I think is a giant middle finger of a challenge to everyone who had trouble with On A roll... hopefully this isn't a pin challenge, especially considering you'll only have a week to complete it.
