The future of MOTOBLUR is a bit murky based on what Motorola co-CEO Dr Sanjay K. Jha had to say recently, but it sounds like he's mainly discussing the brand name itself rather than the concept:
With MOTOBLUR, we have found that being able to convey the value proposition around MOTOBLUR is not an easy thing to do in a 30-second ad spot. We have decided that we will focus on the value proposition of products and not MOTOBLUR as a brand name in its own right. MOTOBLUR continues to be important and I think you will see increased functionality in MOTOBLUR. This notion of push-Internet is going to be very important to us, but as a brand name, which we make matter in front of consumers as a brand name, I don't think that's going to be our focus going forward, but we see the experiences that we deliver is being relevant and differentiating us.
