Driveclub is going to be a strange case. With the Ps+ edition being there at launch it's going to seriously gimp its sales, people will people try the Ps+ version first before deciding if they want to purchase it, while others will just stay with the PS+ version since you can still platinum the game and play with your friends on it.

Well according to preorders, much more want Driveclub : 80k

Driveclubs biggest issue is that part of it is free on PS+, I expect that to affect sales badly.
Sunset Overdrive, to me looks pretty boring so far, and I don't have a lot of faith in Insomniac to deliver something interesting.

So yes I think both will struggle for different reasons. Destiny on the other hand I think will be big, and as we move into the xmas period there are bigger/better games than the two the OP stated for people to bother with.

I know there are lots of COD haters here, but this list is missing the game that is going to have the largest sale numbers which is COD Advanced Warfare.  I would expect, at worst, 20 million sold amongst all platforms.

And anyone that upgrades to the full version is more likely to do it digitally.

Driveclub will have momentum on the fact it is free on plus, sunset overdrive's market is not on xbox, i think, unless microsoft do something drastic, SO might flop, but wont really affect insomniac luckily since ms funded it

Driveclub will be far better received and far more successful but it will be downplayed because of the PS+ version.

I don't want Sunset Overdrive to flop! That game looks so awesome!

Aren't  most of those pre-orders from when Driveclub was supposed to come out months ago?

Probably, but they're still there if that means anything.
