Surprised this is the top comment. Your first link is reporting on an unrelated military program to replace the RD-180 rocket engine. The other four links are all blog spam using the same source: the Wall Street Journal article by Andy Pasztor. Pasztor is well known in the aerospace industry for writing what you might call "speculative" articles based on not much more than rumor.
Fair warning I don't think it has any actual news content. The expected outcome was that Boeing and SpaceX would both be winners, but because SpaceX is always cheaper, Boeing would get a larger amount of money.
It certainly could be true, but the official announcement is in two hours so probably just makes the most sense to wait and see what happens rather than post more speculation.
I found some better sources and cleaned up the links. Thanks for pointing that out. The purpose of the links is to shed more light on what is happening and the relationships among the companies and government bodies.
I actually would be fairly happy with that. At the moment, I think the space industry resembles very closely how the transistor market looked in the 50's. Very few immediate commercial prospects, but an eager government. I think more competition only helps the industry as a whole?
Though from my sideline uneducated perspective SpaceX has demonstrated more success then anyone else at this point.
