Nah, Could be a little inspiration. Since God of War, just about every type of game in this genera has stolen from the series. The single player needed a nice revamp before it got stale. In previous games the weapons outside the Blades of Chaos couldn't compare... Sword of Zeus was kinda cool, but the Blades were just so much better. It looks to me that you'll just have a secondary that you've stolen and you can interchange them out as you see fit when you encounter certain enemies who's weapon you like. Or maybe instead of 3 fixed secondary weapons you find throughout the game, you'll just have 3 slots to interchange giving you a variety of weapons. This would be my preferred method. There is always that one weapon you don't want to give up for another, and this would allow you to keep it while experimenting with others without regretting swapping them out. It would also conform with the button layout of the previous games.
