New SAT coming in 2016

Some big news released today on changes to the SAT. College Board will be going back to the original 1600 score, and the writing section will become optional.

I am very curious what this will mean for admissions– will colleges expect students to take the optional writing section? Will those who don’t be penalized, or at a disadvantage? Additionally, just like the first round of high school seniors who took the “new” SAT with the 2400 score, how much uncertainty will there be over what a good score means?
