Myspace secretly building webmail product

Hot off the press and all secret squirrels at this stage but Myspace are building a webmail product to rivel hotmail, Yahoo! mail, gmail etc. It's a big step given that only 6% of users spend time with social networks mail products. But if users were to migrate to use their Myspace mail as their main account this would be huge for Myspace. Traffic would increase to perhaps double / trebble the current numbers and also increase dwell time massively giving them a huge advantage over Facebook.
