I don't know who he is (nobody does), maybe he is a second account of some Relic worker, somehow he manages to deliver every piece of news before Relic to coh2.org.
For what it's worth, I think it highly unlikely that Relic would release two major patches in one week. I don't think it's ever happened before (discounting hotfixes). I am happy to be proved wrong, though.
FYI, the Tiger gun barrel is fixed. nacho and I just tested it.
