You guys that pre-ordered from Sennheiser and are waiting on your HD560S should be happy that you are able to do so.
Had Sennheiser not taken pre-orders, and instead based their sales on the inventory available at the moment, they would have sold out immediately, and many of you would not be in line to get the HD560S. So consider yourself lucky.
Meanwhile, I think many of us who have been headophiles for a long time will agree with me when I say that in the grand scheme of things, waiting a few extra weeks for a new audio product at first release due to limited inventory isn't a big deal as long as you have headphones to use in the meantime. 6 months from now, no one will care that this happened. And Sennheiser has promised to work on their notifications. So it's all good.
Just be glad you are not Philips fans who waited 6 months after Philips announced the release for the X3 was going to be last January/February.
