It's going to have to cost more than the 35, if it's all they say it is. More glass, and hopefully much better AF.
So, $1100-1200 US street price seems about in line and probable, possibly as little as a grand (one can hope). MSRP of course would be $1500-1600. And in typical Sigma fashion, the price will slowly ratchet down as the weeks go by. Not that I'm waiting for a lower price!
I don't think so- a well-corrected 35mm lens is more complex than a well-corrected 50mm lens; same if they're not so well corrected, a la 50/1.8 vs. 35/2. It would make sense for the 50/1.4|A to debut at a lower price than the 35/1.4|A did.
