The Pros: Guaranteed Longevity for said game, discounted price when compared to buying individual DLC separately.
The Cons: Obvious evidence of work being held back to be release later for an extra fee (SFxT).
Also Companies get your money in advance and then mail it in and release half ass DLC within Season Pass (Gears Of War 3).

The Pros: Sometimes developers strike gold and create fun and engaging co-op/multiplayer experiences (Mass Effect 3). This is generally the exception and not the norm.
The Cons: Usually gaming companies venture into this territory as an obvious cash grab with sub-par gameplay. The Multiplayer mode isn't thoroughly fleshed out and it becomes painfully obvious they should of spent more time on the Single Player aspect.
