Updates are not region specific, you will get an update when the rest of us get an update.
As for when that will be, we do not know.
If EA are in a good mood they might tease something specific on Facebook or announce the next update, but 99.999% of the time we only know that there will be an update when it actually happens.
In saying that, we can make some very educated guesses in some cases, for example, we are pretty good at determining when the next Christmas event will be launched, likewise for Halloween and July 4th, but for all other events, your guess is as good as mine.
Even more so, we are usually provided with some good information when event take-down updates are released, and the update last week was no exception:
"The New Year has been rung in, and the soggy decapitated goat heads have been wrung out. With Springfield getting back to normal, what will be next for your town? An inaugural incident? A romp around the world? A valentine visit from a gluttonous gal? Maybe some military miseducation? You'll just have to wait and find out!"―Update description on iTunes and Play Store
From this we can determine many things, but the standouts are "inaugural" (something to do with President Trump?) and "valentine" (Clearly we will be getting something for Valentines Day). As for when any of this will happen, again...
WE DON'T KNOW
