I'm fine with the 4 teams playing for the national title - committee selecting the best 4 to play as well. But why can't the top 2 seeds get home games? I am really in favor of that scenario. Do they really expect fan bases to perhaps play a national semi final game (ex. the Rose bowl)...win it...then travel again in a couple of weeks to say. (Atlanta) for the title game? That is going to get REALLY expensive for the average fan.
My thought... if the top 2 teams are ranked that way after the "conference championship week" they deserve to host home games the week after. (Thus tying in what most of these directors have been talking about...giving a stronger appeal to the regular season.) Winners to the title game and the losers can play in the Orange Bowl for a consolation game to celebrate their seasons as well. I would rather have that. Plus, would be more cost effective all around.
While I agree with you in that I would also like to see home games, look at the teams who are typically in BCS Championship. Alabama, LSU, Auburn, Oregon, Texas, Florida, Oklahoma, Ohio St, USC, Miami, Nebraska, Florida St, Virginia Tech and Tennessee have made it to the BCS Championship game. Its not like UConn is going to the national championship game and bringing 3,000 fans. I don't think asking team's fans to travel to 2 different bowl sites is going to be an issue most of the time.
