Lenovo accidentally published the product page of the new X1 Carbon which actually hasn't been announced yet. They've since realized their mistake and taken it down again, but yesterday you could read everything about the new X1 Carbon.

Here is a snapshot of the page: http://archive.is/L1o6h

try: http://www3.lenovo.com/ca/en/laptops/thinkpad/thinkpad-x/Thi...

That points to the 4th gen X1 Carbon, whereas the link for the story seems to be about a 5th gen X1 Carbon (which now returns a 404). Lenovo may have inadvertently leaked that page onto their site without intending for it to be reachable yet.
