Magic Keyboard? Buy now or wait for next gen?

I'm thinking about buying another Magic Keyboard, but I'm wondering if I should wait a while considering that Apple has released the new MacBook Pro's with a TouchBar. (Not to mention the missing backlight feature on the Magic Keyboard) Do you think Apple will release a new keyboard next year or are they going to keep the current one for another year (or maybe even more years like they did with the old wireless keyboard)?
