Do we need to wait til October to be able to buy SB3?

Any guesses are just that, guesses but I like this comment:
When is the Surface Book 3 release date?
The original was launched in 2015, with the Surface Book 2 being announced in October 2017. That doesn’t mean there will definitely be a Surface Book 3 in late 2019, but it’s the most reasonable assumption at the moment.
The company is in no hurry to launch products for the sake of maintaining an annual cycle, though it did release a refreshed model of the original Surface Book in 2016 with more 3D power and a Core I7 processor.
There is the slimmest of slim chances that the same might happen this year with the Surface Book 2, but we’re not expecting that to happen: our prediction is for an October 2019 announcement.
