I'd like to know why the dev cost would be so high when phase5 already has a PPC card design done.
I'd say the reason is that it'd require pretty much full redesign, as many of the components haven't been available for years, and/or are not available as RoHS. Also, you'd need to write the software for the card, this is quite tedious and time consuming work, too.
Sure having done previous designs helps, so probably doing it all from scratch would cost even more.
Also that figure of 50keur is probably derived using some highly "scientific" method such as Stetson-Harrison, the actual cost could be very much different.
