Is the Surface Pro 3 shipped with W10 ?

I only ask because I noticed Amazon has option to buy with W10 or 8.1

I was under the impression that the SP3 was shipped with 8.1
and it had to be upgraded to W10.

According to that article it looks like the SP4
will be hitting the market in October.

So I guess I'm going to wait it out .

Thanks for the link, I appreciate it!
