Well we'll know soon enough. As Pyrr said, they don't usually pr these presentations until the day of (although I know there have been a few that have been pr'd a bit ahead of the day).
Maybe this is a case of us getting ahead of them on news - both on her presentation, and on this present data on the EU Clinical trials page.
It's hard to imagine that the EU got it so wrong, so I'd agree with RR that it's probably not a typo. But it certainly hasn't been updated on the US one, and that was verified by NWBO in June. Perhaps she was going to take this Wednesday to announce it, and then it would be updated here. And once again, we got ahead of them.
What would be great is if she gave us some great news on Direct at the same time. That would help mitigate any blow this enlargement to L might have. And as Flipper indicated in his A Alternative, it's really not that "daunting".
