Is this the iCloud login screen?

With WWDC 2011 only days away, the leaks coming faster and more furiously, and one of the big ones might just be shown in that image up top -- purportedly the [iCloud](] login screen, by way of chpwn on Twitter.

Question is, will it replace MobileMe as Apple new internet services portal, or will it be a second point of entry?

UPDATE: And... it's a fake.
