Email going around in which the next Nvidia promo will include vouchers for Rise of the Tomb Raider, starting January 7th, 2016.
Can't post a source, but the news will definitely hit soon.
EDIT: To clarify, the game will be included with GTX 970, 980, 980 Ti, and notebooks/laptops with 970M or above GPUs.
