Dre's "run" as the "God" producer is starting to end, because he's coasting off his reputation instead of continously reminding people why he is Dre.
1) I disagree, since he's responsible for a lot of shit that Interscope puts out - though it might not have his name on it. He's asked to "give up" beats to artists by the upper management. There's a lot of cross-pollination of ideas and music and Interscope, where artists are actively encouraged to reach across to their labelmates and producers to help collectively garner hits for the "team." Timbaland is a producer that REALLY took advantage of this and is working with Jimmy Io's team to help ALL Interscope acts (pop, rock and of course - hiphop.)
2) Dre probably has a contract with Interscope like Axl Rose had with Geffen - where the label pays him an insanely massive stipend until a certain date which thereafter Dre would be in breach of contract and pay Interscope back some money.
You can't play with the fans like that - I think there may be a bigger problem going on over at Aftermath, too many very talented artists have been shelved, I'm surprised that Busta Rhymes' album dropped when it did - but it might've been a clause in his contract to do so, who knows.
3) From what I heard about Busta drama with Interscope (getting dropped by the label) - there was some personal shit going on between Busta and upper management. Busta ain't the draw he used to be... monetarily... so he shoulda kept his mouth shut.
4) Who says you can't mess with the fans? Every time a pathetic PR campaign comes out, they're messing with them.
Expectations to re-create that magic again and again is more powerful of an influence than money can ever be. Money didn't change Dre, expectations did.
5) He has way too many responsibilities. People were doubting him when he released "Chronic 2001." The haters were easily dismissed. He'll call on his proteges to do the album filler for him and it will be a "best of" like his albums usually are, and go multiplatinum even in a recessed recording industry.
