Not at all surprising. He had that UGK tribute back in 2011, then later did the same with Mac Dre, and now Wu Tang. All three have a large hardcore cult following. Drake's way of falling into good graces with them.
Interested to see what song or songs 40 samples for the track. Odd that Rza has nothing to do with it, though. Maybe we'll get a remix from him at some point.
Kinda looking forward to hearing it to be honest.
