Every weekend in March they kept promising the Saipan "later this month," with events geared toward US carrier captains to gain XP and other rewards. Again: it's the only premium US ship hyped like this since the game went into open beta, against the flood of IJN ships they've pushed upon us, and coincidentally it's also the only ship they haven't delivered on time. And now we're all waiting, checking each day, and hoping that 1) it gets released soon and 2) it isn't terrible like every US premium that's been released so far.
"Events geared toward US carrier captains to gain XP and other rewards"
Events are geared towards accumulating data, so they can fine tune specific classes and nationalities via usage of contest data. They aren't about getting free stuff. I realize this may come as a shock, and I do apologize.
And no I don't represent Wargaming or speak for them in any manner and have no particular knowledge of any of the aforementioned.
