Most of the major drum manufacturers don't even appear to have showed up. No Tama, no DW, no Gretsch, no Ludwig, no Sabian, no Zildjian. Maybe it's just easier to list the companies that DID show up. Roland, Yamaha, Dixon, Pearl and Sakae. That's pretty much it.
On the website you sign up for these "events". What are these big events once they go live? They link you to a stupid Youtube video. That's it. Most of them are useless promotional puff pieces with no actual info.
This is one of the FEW pieces of actual new info I've managed to find. Sakae's new Evolved line. (with the quirky badges, blech)
