I have always loved these posters.  I was sad when the new 2015 poster was a PDF of seven 8.5x11 pages, and the Visio was separate sheets, so I got working in Visio with their source data and managed to stuff it all into a single document.

Download includes the Visio (VSDX) and a PDF

I have found a semi gloss poster from Office Depot here for $25:

24x36 is a common frame size, so you can make this suitable for framing really easily!

If Microsoft would like to take and reuse this as their deliverable, feel free.  :)  Also, I am open to any feedback/corrections.
