Here is something to chew on while you wait;

I was not all that suprised when they announced the shift to the 4th quarter, its highly unusual to see them ever release something on time. From personal experience (MPX200) the phone release date and my actual ability to go out and buy it from Orange (or whoever) are often not the same, the MPX200 was released "early 4th quarter" last year but i had to wait until December to get the bloody thing, not sure why but i suspect that Orange had to get all thier customer support in place before releasing it. Possibly you might get it sooner by pre-ordering it here:

This would be a bit pricy as its without contract.
