When is Windows 10 due for release?

[Windows Central Question]

I want to get a new computer and obviously would like the latest operating system ie windows 10 that is why I would like to know when it is coming out

Summer this year.

It'll be a free upgrade from Windows 7 & 8, so you may as well buy a computer now and upgrade later.
