Crash? GT? Zelda? Come on, guys. It's not like COD: WW2, Destiny 2, Battlefront 2 and Fifa won't beat these guys by a big margin, we have to be realistic.
If we are talking about exclusives, I don't know. Zelda has a best shot than GT at doing this, since it is selling since Q2 while GT will have just some months. It also depends if Poliphony will make a hit or if they will once more get a lukewarm reception (with their recent record and the fact that this is a beefed-up "Prologue", I wouldn't get my hopes high).
Crash will do good numbers, but I believe that the results in the UK aren't representative of the rest of the world. Well, if they indeed are and Crash manages to outsell GT and Zelda, you can bet that Activision will have a new Crash game for 2018/9.
