Drive club was supposed to launch with the PS4 but got removed. It seems like the hype may have been hurt a bit because of that and also numerous delays after. However, the game is supposed to be this realistic version of ridge racer with an online focus, and screens show that it looks decent. Considering GT7 won't come out for awhile and GT6 was uh, something, this may have a chance to be big.
As for Bloodborn, I am a bit mixed on it. Souls fans MAY go to it, but I don't think it will push too much for a variety of reasons, some including the fact like the "Souls" is no in the title, Dark Souls 2 just game out, Souls is actually not that big of a franchise, and it's exclusive. Some people say Miyazaki will help with this being big, although Miyazakis popularity has always been largely inflated and i doubt that will do that much as well (How long did it take Ni no Kuni to get past 1 million again?) But considering the upcoming drought of big PS4 games, this may also have the Killzone Shadow Fall effect of people buying it anyway. So there are a lot of factors that can make this and prevent this game from being big.
