i just spoke with someone from Lyric, they said that this will be in May 2008 but no venue yet. they just confirmed that Benny Greb is the clinician. they also said that they would like it to be in Shangri-La.
another good news is, DW would also have a clinic this August but that's the only info i got from Lyric.
2008 is really awesome for us drummers!
