Aha, found what I was looking for.

Okay, CoD is not a MOHAA sequel, but it's made by a bunch of the same people. The team that made CoD is Infinity Ward, and from their website I get the following tidbit:

Infinity Ward was started by 22 members of the Medal of Honor Allied Assault team, including all the leads.

Basically that's all I was looking for, I'm going to get the same level of quality and attention to details in CoD that I got in MOHAA. Maybe not a sequel, but it might as well be.
