Now that the new Windows Phone 7 Series has been announced at MWC10, Microsoft has already put up a website to demo the new UI. Also, check out the quote in the screenshot above!
You can view the demo here: http://www.windowsphone7series.com/.
It covers most of the new layout features that were discussed during the press conference and lets you see some things in action.
Thanks to forum user kev.schu for the tip.
