Okay people - I just got off of the phone with Sega's sales line. They told me that NO - they are not going to be selling the Sega broadband adapter. It will not be available in the US at all from anyone - including the Sega.com store until May.
I have heard from various sources that the Japanese version of the broadband adapter does indeed work on the US DC, but I cannot confirm this as I have yet to see it with my own eyes. Maybe someone on this site can provide some enlightenment concerning this.
I have seen the Japanese version available on this site. But, it is pretty expensive, but worth it if you don't want to wait.
