Seatool Housing for Canon 40D/50D

Couple question need some help!!

Is the Seatool 40D housing can also fit a 50D inside?

both camera looks like the same in dimension and buttons!

Beside the Dome port from Seatool, is there any other brand dome port can work with this housing along with Tokina 10-17 fisheye?

Thank you

This would seem to indicate that it does.
