I don’t know that there is an added delay. I think the closer they get the more they are going to stick to their July/August time frame. That was always the official line with a sub context of (we hope to ship some earlier). July/August was the primary delivery window (as of November’s delay). As shipping starts to become more of a reality I don’t think they will say anything but july/august until the first unit ships, and if it’s earlier they will yell, “Suprise!”
I don’t think there’s a delay, they are just getting tight-lipped, which is to be expected.
