Announced in Oct 2010: The nonprofit Marine Well Containment Co. is to be ready in 18 months http://www.enterprisenews.com/x1070618851/OPINION-Oil-spills-Next-time-industry-will-be-ready?template=printart
Still not tested, and it is going to be hard to test given that there is no simulated well blow out to hook up to; so first test is likely to be the first time, if ever it is, needed. What could go wrong?

Not tested yet? Where do you see that?

Testing to hold the pressure is not the same as using on an actual blowout.

The 15,000 psi unit was ready for use back in February 2011.
