I suppose it's a good thing that Disney reduced the numbers of surviving Jedi, the numbers got really high over the years in the EU.
Five Jedi who survived Order 66, according to Disney:
5. Anakin Skywalker (not if you ask old Ben though)
4. Kanan Jarrus
3. Ahsoka Tano
2. Obi-Wan Kenobi
1. Yoda
Quinlan Vos is still a possibility as he isn't dead by the end of "Dark Disciple". Also Mace Windu is in limbo because if Maul (canonically) can survive being cut in half with a lightsaber and a fall down an unknown distance, and -still- be alive and come back to be a badass, so can Mace, plus you never see a body and we all know what that means.
It just seems statistically unlikely that out of the 10,000 Jedi that were present during the Clone Wars only five survived Order 66.
