"Some" have said that there is a lot going on behind the scenes just now, but I have no idea what they are doing. If I were to guess I would guess current efforts is directed towards lobbying ISAF and IOC to include a multihull for 2012.
The Tornado (and other cats) are at the same time doublehanded dinghies and high performance doublehanded dinghies; while the A class is at the same time a singlehanded dinghy and a heavyweight singlehanded dinghy. Besides, the Moth is also a singlehanded dinghy and the 29er is a doublehanded dinghy...
This leaves space for more negotiations.
