I would hope that if they did do that and it pushed the data collection period and unblinding out another 2 weeks or so, that NP would have let us know seeing as how he did say he hoped to do it last week. 2 more weeks of complete silence without explanation would not be cool on his part, and who knows how low the SP will fall in the next 2 weeks if we are told nothing!
Granted, we all hope that no matter how long it takes to get the data, the SP will go parabolic in no time, but until then, this is not fun for anyone.
