Has a timeline for the announcement been mentioned in any of these articles? So far it's only been that there will be some kind of announcement, but I can't find any suggestions of when.

Sometimes I wonder if these leaks are strategic as a way to say "hey, if this is you, last chance to come forward before we talk about this publicly"; maybe a little more "are you suuuuuuure these aren't your toys?" before someone finally comes out and says "We found this weirdly shaped hunk of metal and it seems cool but we don't know how to make it".

The conspiracy theorist in me hopes that we found something on Mars, and that's what's been causing all the expeditions out there recently.
