The Legend of Korra
Studio Pierrot animated the first two episodes... be still my heart! I knew it looked a little familiar! Just slightly and only in some places, but familiar nonetheless.
FYI, most people who watch Anime should be at least somewhat familiar with Studio Pierrot. They're know for many things, but NARUTO (and NARUTO Shippuden) are the most well known.
Just sit back and let that sink in for a moment. Think of what glorious fight scenes await us! I means Studio Mir (who animated Korra's first season) is still animating the show as well, but just knowing Studio Pierrot is animating some of the episodes... I... I just... ohh~~ *swoons*
