Watch Dogs' successful launch is why a 3rd party should not go exclusive like Titanfall.

Horrible example, Titanfall is a completely different situation than Watch Dogs. Plus it would have costed much more develop for three different platforms. Titanfall has sold over 2 million on Xbox One alone, it did great.

Porting a game once all of the assets are done isn't so bad.  God of War Collection took 15 weeks.

There is also a quote from Ubisoft that porting a game should cost less than $1 million USD.  That is a very small number compared to the number of lost sales.
