LOL. btw, MSDN just released SQL2014, announced ("a handful of hours x n") ago, so make a wide guess.. also, NTmartha(AKA canouna) is still down, don't know it's a take-down or self-withdraw.
If you don't have a subscription, or a genuine key and/or legal download, and you can still obtain it, then I would suggest it is a leak, whatever semantics are applied.
Guys it's not a leak when it hits MSDN. At that point it's just a MSDN file. It's a leak when some disgruntled employee copies an internal file to an external network. MSDN is pseudo-public since it's just a paid service. Would someone at a paid cable channel be shocked that people were sharing their videos on the internet? No, that wouldn't be a leak. That's just someone who paid for something, sharing it with strangers.
He showed Enterprise Mode being available as an option in the Tools menu of IE11 - that is not there with the update we got from WZT
