I think there are a few games that will help drive sales either individually or as a group:
1) Horizon
2) GTS
3) Destiny
4) Shenmue 3
5) Crash Remake
6) FF VII Remake (if it releases on time)
7) Star Wars BF2 (the movie hype will help)
A price drop to go along with this will help will massively.
If they get RDR2 marketing, that will be a bonus.
