I don't think the situations are comparable. Maybe they're cool, as you said. I'm just basing it on Timbo pulling a Kanye and falling out with Hov...maybe the same happened with Nas. Breh isn't getting noteworthy placements anymore, just seems like something is up. You guys made some other points that suggest you could be right, like Timbo being at the Echo vid premier (I didn't know that).
Timbaland still gets noteworthy placements. He is working on Kanye's new album. He's been in the studio with Snoop. There was just this video of him working with Ludacris apparently helming Luda's next album. He was on Mariah's last album as well. Beyonce just tacked on a Timbaland produced song from 2013 to that Homecoming live compilation she put out.
Even Large Professor was confused as to why Nas hasn't released the music he did with Timbaland. He even described the songs as crazy. Huge deal coming from Large Professor considering he didn't consider "One Mic" to be great and was very critical of Nas's past work with Tim ("You Owe Me" and his verse on Missy's "Hot Boyz").
