Getting updates to consoles is certainly slower than on PC, at least because both consoles have their own approval process of some sort on the updates, but likely also because some things need to be reprogrammed or tweaked differently. Because of this, FS likes to do somewhat bigger updates on a slower schedule for consoles.
There’s also the thing that they use PC as bit of a testing ground for certain things, to iron out platform-agnostic bugs and other issues (again because the process is more complicated and time-consuming for the consoles, and this way they don’t have to make the changes multiple times), so that also adds to the time it takes for the consoles to get the updates. As far as I know, no content beyond mods (and even those are possible in some form) are planned to be left out of the consoles completely, but it will take more time for the various reasons mentioned. They will likely come out in bigger batches, though.
As for the events, I’ve understood that for the Mondstille there have been quite a few snags, and this one is (as others said) specifically for PC at this time. The consoles will likely get their drunken rampages at their respective release dates (if things go as they’re supposed to, anyway). Remember, it won’t be available for PC indefinitely either.
As a final thing, I’ve personally gotten the impression that FS in general is less experienced with the consoles, if only from the amount of troubles they specifically seem to have, and certainly the console team is small and have their hands full constantly.
