Blizz stated in a watercooler that they're using the 1.12 database as a starting point. I don't think it's a stretch for people to assume that most game features and mechanics will be in their 1.12 state. The kind of stuff I would expect to see reverted would be numerous AV changes, but I seriously doubt class mechanics are going to be reverted. I'd be surprised if the threat changes that ruin pre-naxx encounters are reverted.
“To fill our pool of beta and stress test participants, we’ll be choosing dedicated players who meet select criteria from both the WoW Classic beta opt-in and the standard Warcraft beta opt-in. Participants will also need to have an active subscription or active game time on their Battle.net Account. While opting-in to the beta is the primary way to make sure you’re in the running to join the test it doesn’t guarantee an invitation to the closed beta test. We may also consider additional factors such as how long a player has been subscribed to the game so that we have the right mix of players to ensure great feedback toward making WoW Classic the very best experience for the community.”
Blizzard said it will choose players who have active subscriptions to the regular game based on a variety of factors to help them test the beta. It could be based on your PC, your commitment to the game, or just your luck. If you get in, you’ll likely receive an email, but if not, you can check your launcher. And remember: as with any beta, your progress will not be saved for when the game launches later this year.
Nov 15 I Don't Have Time To Reach Rank 11-14 I Don't Have Time To Reach Rank 11-14 and this is perfectly ACCEPTABLE! I actually like the fact that rank 11-14 is extremely hard to get and time consuming. I don't care if it's not about skill, it is very RPG feeling in the fact that, the people who put in the most time and effort spilling the most enemy blood are the ones who get the best rewards. as somebody who will NEVER have a chance of getting those ranks and items because; 1. I do not have time to do it 2. even if I did have time I still wouldn't do it because I mentally could not farm BG's that many hours for 3 months I support the PvP system and think it is great, and acquiring the hugely powerful items is a big reward and a status symbol. in Classic WoW the game is less about YOU and more about your guild. even if you are not the person to get rank 14, or a Legendary item it still feels awesome when your guild mates get them because it will make your guild stronger.

Dustin Bailey recently interviewed senior producer Calia Schie and game director Ion Hazzikostas for PCGamesN about recreating this kind of environment, and it includes some equally wonderful lines, like Hazzikostas saying “It was surreal almost to see our art director [Chris Robinson], who is one of the best artists I’ve ever met, and someone who pushes for perfection and refinement in everything that we do, advocating for actively working to make things look worse.”
WoW: Classic is scheduled for August 27 (technically August 26 if you're in the Americas). The soonest that you can play it is starting in May, during Blizzard's scheduled stress tests. To opt-in you must have an active subscription on your Battle.net account. If you do, go to Account Management and select the Wow Classic beta. Keep in mind, there will be level caps during the test. The schedule is as follows:
