Don't see it happening. Uncharted has been getting bundled from the first one because it was always intended to be mainstream. God of War is an R rated franchise. If it becomes mainstream it still would be a niche audience with little room for expansion like Dark Souls so Sony wouldn't push it as much. They have another mainstream game coming instead with Spiderman.
God of War always was extremely mainstream with its macho hero, brutal but simple gameplay, and simple themes. They're changing things up quite a bit this time, so I would not be surprised to see massive bundling.
