I suppose the announcement could still happen today and even as late as after hours but the longer this drags on, the more antsy folks are going to get. These guys have taken forever to get this deal done. Just hoping the wait was worth it but we need something saying it's officially done.
My post is only my opinion, I recommend you always do your own DD! I am not a licensed broker or a professional by any means, so take what I say as entertainment value at best.
