First time hearing about this...Microsoft will be shutting down the Hotmail name and its new moniker will be...Outlook.com
I believe if you sign up for Outlook.com using your old Hotmail username you will still be able to access your kept email and still enjoy the new features (I am guessing the domain email will be
username@outlook.com instead)
I saw a few screenshots and it looks like the Hotmail view in the Windoes 8 betas...not a bad look but I didn't want to see Hotmail go.
