I'm guessing this will start out as 1 TS and with no characters (the restaurant will provide assorted ambiance factors as a tradeoff).
I'm also guessing it will be a la carte full service and prices will be high (for 1 TS). Think average entree price of at least $30, with more expensive entrees at least $35 (Disney is always looking for ways to entice people to buy a dining plan and making prices high while at the same time starting out at 1 TS accomplishes this).
I'm guessing food quality will be somewhat similar to CRT (anyone expecting true signature restaurant quality is going to be disappointed).
If demand is crazy high and stays that way (like the old days of CRT when you had to use an atomic clock to get an ADR) it will most likely get bumped up to 2 TS at some point. But that won't mean the food quality will be any better.
Sorry if this sounds cynical (believe me, I'm as curious about this restaurant as anyone and hope it exceeds my expectations).
