20-30k is about what you can expect from core Nas fans. So if this is going to be another project that comes like a thief in the night with no promo and no features I don't think anyone should expect more than that and the street team shouldn't criticize the fans. IMO there is no better way to maximize the return on his investment from these projects than to bring in an A-lister or two to help put the spotlight on his work. Collaborations don't just help with sales, they are fun for listeners. Think of all the collabs that could have happened in the past that didn't. He missed out on the Miseducation of Lauryn Hill recording sessions, didn't get to record with Pac before he died, "should have did the remix verse on Gimme the Loot for Biggie", why not tap in to today's highly regarded guys? Don't him and Kendrick share a manager? Certain things make too much sense and I dont get the pushback to the idea.
The voice of the Nas street team is a chick that can barely string together two coherent thoughts with a couple thousand followers on twitter. Again, the voice of the Nas street team has an audience of under 3k people. Features obviously would move the needle in the sales conversation more than her bytching on twitter begging working people to make posters to promote the album or follow these intricate methods of streaming - and that's coming from someone that supports every Nas project with his wallet.
