I've been hearing buzz about this as well. Was waiting to post until there was a press release though...
We've seen more and more consolidation in recent years so the concept here isn't exactly a huge surprise but the players involved may be. My guess is that this won't necessarily affect much on the consumer side, though we may see a bit more in the way of brand collaboration (DW 808 pedal?

). I'll be curious to see the effect this has for retailers when it comes to ordering and distribution. I also wonder if we'll see some sort of deal with DW producing the shells for the Roland electronic kits that feature shells (I believe Remo is making those right now...).
