Is Sony even trying?

After claiming that rumble was "last gen" when Microsoft had it and they didn't, they announced that they were going to include it.  Good news right?

The problem is that they also announced that they aren't shipping it until Spring 2008.

It's pretty basic stuff that you don't pre-announce hardware upgrades until you're almost ready to ship them. 

On the one hand, they're claiming that they're going to beat XBox 360 sales by March of next year, and the other hand, doing something that will definitely encourage some buyers to wait until Spring to buy.

I don't get it.
