In a world where every single other MMO out there is using some form of microtransaction, we would be foolish not to assume that they will exist in conjunction with TESO. Even games that are subscription-based have microtransaction stores. This is the announced plan for "The Secret World." It would not surprise me in the slightest if it ends up being the announced plan for this game as well. And all who read this would do well to prepare themselves for that very real possibility. I've given up on bucking the industry on this issue. MTs are a very real part of MMO revenue generation, and they are not going anywhere. I would be more shocked if we find out that TESO won't be using them. Why? Because they WORK as a means of revenue generation, And whatever works to generate money is what the suits in marketing are going to insist upon. And make no mistake, the hierarchy for most corporate-run development companies goes like this:
Parent Company Corporate Suits
Marketing Department
Development Company Corporate Suits
Development Team Lead
Developers
And the Marketing Department is going to make bloody well sure that they never end up in the crosshairs when it comes to bad marketing decisions. That will be for the lead developer to deal with. And guess what? In typical corporate fashion, the lead developer would have signed something that forbids him/her from saying anything that would paint his employer in a bad light. He'll have no choice but to take every virtual rotten tomato to the face, doing his best to keep he developers under his charge out of the line of fire.
So yes. Expect microtransactions. They WILL be there at some point, even if they aren't there at launch.
I should also point out that a subscription is in effect a microtransaction set to recur on a monthly basis. And technically so are expansion packs you buy.
