Well I wasnt telling you to lose your doubts, but until you hear things officially then, you know what they say about assumptions.... being the mother of something or somesuch. Paradox will issue a statement if things get cancelled - like what happened to the ill-fated Magna Mundi.
So if anything Id wager that the extra time being spent on MP is probably alot of testing going, given Paradox's recent stance and movement towards quality assurance.
Meaningful QA is a great thing! So too are updates on timelines when deadlines are missed. Like others, I found the "end of the month" target to be surprising given the size of the (apparent) task. Paradox maintains multiple tweet accounts, facebook pages, and these forums. It doesn't seem like a status report/progress update would be that difficult to deliver.
Given the dark tone of some speculation (It's late?! OMG the game is doomed/we were lied too/PITCHFORKS!), I find it surprising there hasn't been some official word.
