Check it out, the Thor Motorcoach website has been refreshed with a new layout and new colors:
Thor Motor Coach - North America's #1 Brand of Motorhomes
Browsing through the Axis/Vegas pages it doesn't look like there is anything substantially new (although they do have 2015 literature for the Vegas, but not the Axis including more pictures of the different floorplans--you now have to scroll down to the bottom to see the gallery).
