So TSMC was ready for volume production of 40nm November 17th why would it take until Q2?

LP or GP?

Also from your own link:

So, when will 40nm GPUs come out? That's tough to say, but AMD's 55nm Radeon HD 3800 graphics cards came out roughly 7.5 months after TSMC announced the "readiness" of its 55nm process last year. Extrapolating from that, you can probably expect AMD and Nvidia to launch their first 40nm products in the first half of next year.
