Well the RTM was leaked and Metro is no more, it shall be now called "Windows 8-style UI".
What's new, some nice lock screen images (wow really?!) and some nice metro Windows 8-style UI backgrounds now with color on top of shapes! You do have to have an activated copy though, so unless you have a licence from VLSC you can't get them yet. Which is disappointing because I want to get metro Windows 8-style UI so I can have Microsoft made images and not use my own!
You can also use your mouse wheel to scroll the metro Windows 8-style UI backwards and forwards, however you still can't right click anywhere on the metro Windows 8-style UI interface (apart from to get into 'all aps'), so to access device settings like network, you have to go to the metro Windows 8-style UI interface, right click to see 'all aps' which happens to be the things you want to see from a start menu and then find your way to network settings (very simple and easy :/).
Aero has been removed and there's no options to turn it on (unless you need to activate, but I doubt it), there's also no metro Windows 8-style UI settings tile, so you need to click your account name and get to settings through that.
I also played with pinning programs to the taskbar, which I may say is even worse than I thought it would be as hard as that is to believe. Meanwhile desktop icons are even worse, to add icons to your desktop you're going to have to use the file explorer and find the exe's to send to desktop.
Will wait for a license to try the special background images to make my final judgement, I can always be swayed by licensed images that rock my eyeballs.
