WHAT WILL CHANGE? (AND WHAT WILL STAY THE SAME?)
Q: Does this mean the updates are over? Are you going to stop releasing free content now?
A: No. Our plan is to continue updating TF2 just like we always have, adding free maps, game modes, new features, and more. The Mann Co. Store is simply an alternative way of obtaining items that other players can earn during gameplay.

Q: Are you going to start charging for other kinds of content, like maps?
A: No, we have no plans to do this. Segregating players into groups that can't play together, based on who bought what, is something we'd like to avoid.

Q: Will I have to spend money to remain competitive?
A: No. Any items affecting gameplay, and even most purely cosmetic items, will still be obtainable simply by playing the game.

Q: Did you adjust the drop rates for existing items?
A: No. We haven't made it any harder to obtain existing items through gameplay.

Q: Why have all my items switched to "Vintage" items?
A: Some items that used to be rare will become more common when they are available for purchase. We wanted to give players this option, but still recognize people who obtained those items “the old-fashioned way” in the past. So we decided to perform a one-time conversion of all the old items into "Vintage" versions, which will never be attainable in the future. This way, those older rare items remain rare (in fact, they're even rarer, because they're limited editions now).

Q: What about items I earn in the future? How will others tell them apart from purchased items?
A: There are not currently any plans to make this distinction visible to other players. However, purchased items are not currently tradeable or craftable, so there's still a benefit to earning your items "the old fashioned way".
