Portsmouth Postpone New Stadium Plans

According to the bbc website, due to the current climate Portsmouth have postponed plans to build a new stadium and will redevelop Fratton Park instead. According to the article they would still be looking to build at a latter stage. I find the decision to redevelop and also build a new one in the future a little bit strange: http://news.bbc.co.uk/sport1/hi/football/teams/p/portsmouth/7953616.stm
