You need to look around more.
Medieval fantasy is not at the top of publishers wish-lists right now.
New medieval fantasy is getting pretty rare, actually.
I'd recommend something like:
Felix Gilman's
The Half-made World
Anthony Huso's
The Last Page
China Mieville's
Perdido Street Station
Guy Gavriel Kay's
Under Heaven
Tim Powers'
The Stress of Her Regard
Daniel Abraham's "The Long Price Quartet"
