I will be quite surprised if this prediction won't turn out to be correct!

PS4 user base when Watch_Dogs released > XBone user base will be when Destiny will release (unless anyone thinks the XBone will jump to 8M in the next 45 days)

So, I can't agree with this as a reasoning for XBO Destiny outselling PS4 Watch_Dogs. Can it happen? Sure. It's going to need a near 50% attach ratio to do it, but it can happen.

Probably.

Also Destiny PS4 > Watch Dogs X1.

Yes, and Destiny PS4 > Destiny Xone.

Hmm, this is weird, some people saying its obvious and some saying it will be hard. Maybe this wasn't as tame of a prediction as I originally thought.

Yeah I could definitely see that happening. Most of the Xbox crowd will try it cause its a FPS and its made by Bungie.

I'm gonna say... Yes.

And then comes Destiny(Ps4) and outsells Destiny(Xone). That's just how things go nowadays, i guess you could call it "Destiny". See what i did there... anyone?

Oooo, interesting... given the install base advantage even looking at the PS4's Watch Dog days compared to the Xbox One's Destiny day, on the surface tricky. But considering Destiny is likely to have far better 'legs' in terms of continuing to sell after the initial release, I must agree with this prediction. ^^

Sorry, didn't saw that part... Anyway, it's good to start a discussion about WD and Destiny since it's probably the better comparison to try predicting Destiny sales.
