No leaks, Sim Guru tweets or confirmations about the next DLC?

I mean, on the subject of Bands, I'd prefer Rock Bands over Boybands (I also prefer them musically, unless you want to stretch it and call The Beatles or Duran Duran "boy bands") But I'll take either. Or even Marching Bands.

Ever since Spark'd, I've kinda been hoping for a way to create my own version of Dr. Gluon's Bubble Bois...
