Just to update, they're on sale at Amazon.com from a THIRD PARTY seller with free shipping for $199.99 as of this post.  I caved and bought a pair, I'll try to post some pictures and a review when I get them in and do some testing.  They will mostly be used for PC gaming connected to an XFi card...

I emailed them and they said:     Quote:   So then I called this past Friday and the person I spoke with on the phone gave me the information in my above post.  I could have bought it right then but as he said, the retail partners will usually sell the same products below full...

Quote: I think you'll like the PC360 better, every review that has come out of Europe like them better then the PC350.  They are "Open" so the sound stage is larger but they let in a bit of outside noise.  I plan on buying them as soon as they hit Amazon's website and will be using them...

The PC-360 is finally available directly from Sennheiser if you call them for $260.  They are supposed to be shipping out to retailers (FYE, Amazon, etc) soon as they just got them into Sennheiser HQ in the US.
