MB, I also hope they are getting better public relations advice than that for the AF press release.
The best practices playbook is that you only show up to a conf in person if you are worst case going to stand pat on previous info. Given the same-day nature of this, IMO this indicates some late breaking good news, i.e., found out yesterday. Most likely possibility for Mar 27 is news that the ASCO abstract was accepted. Then they also can take the opportunity to enhance the impact of the German approvals and give some more detail on the expected process forward there.
Bad news is never done like the above. Bad news would have been a PR after hours Friday.
And IMO no way AF is affecting any decision making of whether to do a conference. GLTA
