The plan is for every NFL team to play abroad over then next 16 years. I think the idea was to have 2 per year and that way each team woud have 1 home and 1 away over the 16 years so in the end it all balances out.
I'm not sure on this and I can't remember the source but have a look at some of the forums at www.nfluk.com as there has been some discussion there I believe.
It states it all quite clearly here: http://cbs.sportsline.com/nfl/story/9923505/rss
"Over the next 16 seasons, each of the league's 32 teams will participate in a regular season game outside the United States. "
EDIT: I guess therefore, in effect 16 teams will lose a game on home soil
