The executive is quick to note that these trials aren't necessarily a sign of things to come. If they are, however, you may have to pay extra to get unfettered service; Cohen notes that the company is "looking at" adding unlimited plans to the trials. It's unclear just what those would entail, although the overage-based model from the trials suggests that you'd pay a premium over normal offerings. That's in sharp contrast to Comcast's acquisition target Time Warner Cable, which offers you a discount if you accept a cap. It's entirely possible that Comcast will forego usage-based pricing, particularly if it wants to please regulators worried about attempts to stifle online video, but it's obvious that the business model is at least under serious consideration.
