Destiny won't flop. It CAN'T flop. Why ? Because it's a FPS.
And it turns out that a new IP in the FPS genre, especially when it's developped by a famous studio, never flops.
And Destiny is edited by Activision (=> CoD fans are potential buyers), developped by Bungie (=> Halo fans), it's a Sci-Fi game (=> Halo fans again + Sci-Fi lovers), it supports CoOp in the campaign, it has interesting online features, etc...
On the paper, this game looks like the ultimate FPS experience. Will the game be great ? Maybe. But will it flop ? No way.
Look at TitanFall for example. A new IP, and the game isn't even that original (just add jetpacks and robots and let's go). But it is doing really good in terms of sales.
Not to mention CoD, which still sells tens of millions without changing a thing, Battlefield 4 which was broken beyonf belief but still was a success, etc...
Just because you have an opinion doesn't mean you are necessarily right.
