I somehow don’t think this is how Microsoft planned to announce Power Pack 2 is coming, it looks like a bit of a slip up to me but the cat is out of the bag now:
Australian magazine APC recently interviewed Stephen Leonard, Senior Product Manager for Windows Home Server regarding plans to release “basic” and “advanced” versions of the product in the future. Whilst splitting the platform into two SKUs is still under consideration (potentially with more entertainment focused features in the advanced version), Leonard confirmed that the V2 release will be preceded by a second Power Pack update in the middle of next year.

So Ian,
I’m in the market for a WHS. Would you hold out now until the full plans for the V2 release come out? I will be going to windows 7 for media center on a couple of my machines so it seems to make sense to hold on!
You’ll be holding out for quite a while if PP2 isn’t until the middle of next year and V2 sometime after that (presumably at least another 6 months or so).
I would not wait for a V2 release, WHS is a great product and you can get the benefit from it now
