To address Greg's concerns;
Tinker might be too good, but if we're going to talk about cards that are too good, Brainstorm is currently unrestricted, and we can certainly start there. Tinker finds Memory Jar, Karn, Mishra's Helix, and not much else, really. It's possible that there's some incredibly busted Tinker deck out there, but right now, I don't think there is (I think there's a good Tinker deck out there, but not one that's better than some of the other decks in the format).
Power is an important addition to the format because it sets a base standard for all decks to compete at. You have to be able to fight Ancestral Recall, Black Lotus, Timetwister, etc. To get to ProsBloom, while the deck was great in 1996, it wasn't a player by the time 2003 rolled around. Off the top of my head, the major players in 2003 were Tog, BBS, TNT, Suicide Black, Sligh, Keeper, and a few other decks. Modern TPS exists nearly untouched (and I believe is probably the best deck of the format). Combo may force Brainstorm onto the Restricted list down the line, as four Brainstorms and six fetches is pretty powerful already, before you subtract Mental Misstep, Flusterstorm, Mindbreak Trap and a slew of other answers. An adjusted TPS scares me a lot more than the old Rector/Bargain decks.
By no means do I think that I've created a perfect format. There are going to be problems, and I expect things to be a little wonky before they're smoothed out. More than anything else, right now, what we need is people playing the format to try and get a handle on what the format has in its favor, what detracts from it, and how to fix it.
Results matter, and results will be the basis upon which restrictions and unrestrictions are made. If TPS is as powerful as I think it is, and it's some unstoppable force for the first five months, it's going to get hit. The same is true of any other deck in the format. In current Vintage, people may hate Shops, or Dredge, or whatever, but I can promise you that nothing is worse than the Ritual pillar being overpowered.
Anyways, to get back on point, I'm really looking forward to the event I'm running at Depot on 8/7, and I will bring a couple of decks with me to Waterbury. I'll play, and support Ray, but Classic excites me in a way that Vintage doesn't, and can't right now.
