If Youtubes has predictive value for sales then there's got to be correlation data across a large number of games, which includes Titanfall. You can't just take KZ views and then extrapolate directly to inFamous.

There probably is a predictive model that could be created that links pre-launch youtube views and intial sales. But there are probably so many variables and complexities that it would be too difficult to costruct the model. Lots of Youtube views probably means good sales. But that's about as accurate as you can be.

Yes there are many many variables, hence I eliminated almost all of them.

Killzone and Infamous.

Both PS4 exclusives. Both primarily featured on the same youtube channel. Both have videos promoted by Sony as ads.

A 2 game data set, even controlling for most variables, is not enough to establish a good predictive model.

It's not. Best we can know is Infamous will probably sell better than Killzone, but even that would be huge for infamous.

In the op however I just made assumption after assumption in order to get that 4 million figure.
