In therm of absolute console sales probably Bloodborne, it will boost the PS4 everywhere including Japan for a weeks, so let's say 100k PS4 sales extra due to bloodborne and let's say an average 33k in he 3 weeks folowing.
People why buy the Xone in holidays due to halo, tomb raider effect will be limited but will guarantee a 100k extra console sales
For Zelda it will sell 50k consoles extra on launch and 20k for the following 3 weeks and that will probably be it. Zelda has never been a great system seller, especially not on a system which isn't selling at all, like the GC.
Please excuse my (probally) poor grammar
