I have installed the beta. The only new feature I now have, is that I'am not able to move to a blank page anymore. I dont see anything of the rest.
And when moving a page, an explorer task gets active for some seconds, it appears in the taskbar. But when active, it is possible to close this task and it never appears again, probably till the next restart. Everything is still working fine though, may nothing important?
I use Win 8 Pro 64bit (yep Win 8, which I kinda like now).
Edit: It looks like, that I do have everything, except the page indicator.
