Well, apparently eCost is also PCMall, MacMall, and even a few other stores, and I've been hearing a consistent date of postponement. The last time it was May 28, and then the latest I was told they weren't sure at all. I ordered that sucker March 19th, and they still can't tell me where I approximately am on the order list? I'm just not going to put faith in them when something is actually needed. My E-10 purchase went ok with them, but that was 4 months after the E-10 was released. eCost's inventory is pretty accurate when something is in stock and I have ordered other stuff from them before, so I'm still staying with them for some other purchases.
For something like the 1D MK II however, I should have gone through B&H. Live and learn I guess.
In any case, I'm just sitting back and waiting patiently. It's probably better I (and you?) get a later manufactured MK II anyway, since there are a few quirks in it, in addition to EVU and DPP.
