I just came across Charles Weibel's Development of Algebraic KTheory until 1980, and found it really helpful. Is there been anything analogous which surveys the developments in the last 30 years? I'd be particularly interested in understanding links (if they exist) to motivic theory, geometric Langlands and higher class field theory.

I recommend the Handbook of Ktheory. It was published in 2005 and Part II seems to contain what you're looking for. 


I would suggest the lectures of Friedlander and Weibel: "An overview of algebraic Ktheory" in Algebraic Ktheory and its applications (Trieste 1997), 1999; MR. The later lectures include the modern point of view in terms of motivic cohomology and so forth together with connections to various theorems like the Milnor conjecture.
