I'm not sure of how much testing they have done on the new SAT, but there clearly has been some. Talk to any kid who took a recent SAT (say January or March), and they'll tell you that the experimental section was weird. The questions were nothing like the current SAT questions.

I think that smart kids will still do well on the SAT, and not-so-smart kids will continue to perform poorly on the SAT. The math questions look like they are critical thinking type questions. The kid that struggles to understand a basic textbook algebra problem will not do well. A preliminary look at the new SAT math can be found here:

And we'll get some insight into the new SAT test/scoring scale when the HS Class of 2017 takes their junior year PSAT in the fall of 2015 - it will be the new SAT format.
