The question is raised plenty times now, The answer as to why the dilution now is quite simple..
GTCB expects an EU approval for sure, however they are not betting the farm on it... earlier emissions showed they go for continuity first...and only than count in any possible pisitive extras..
earlier they had cash to last them till mid 2007 or so... well, should for whatever reason the eu approval face problems than that would leave them in a very weak position to continue and complete the FDA application..
They definately choose for safety, so regardless of the eu outcome they will survive all the way through the end of the FDA application process
