"Any updates as to when the S2 Prewar Inspired Set will be in?"
I was told by my dealer last week or so that Lionel received them Nov 7, and that they (the dealer) should be receiving them "soon".
As precise as I can be, I'm afraid.

"Yes, the catalog price is $999, but street prices were as low as $800 at the time of preorder."
Yes, they were - and I think that they have as much "value" as most anything else in this hobby.
