I had a briefing session a few months back with the company. Parkview have only owned the site since 1997, and have been tied up with all sorts of planning hassles, problems securing the whole site, planning enquiries, legal challenges and all sorts. If they haven't pulled out yet, I doubt they will now. And there's lots of materials now being delivered to the site.

Re: transport. They're meant to be spending £10m on beefing up the BR station. And also intend to do some sort of river taxi thing. Given that it's supposed to be completed in 1012, they can probably piggyback on olympics stuff.
