All Windows Home Server devices to receive security, media streaming updates

Remember those security / media streaming / Vista x64 updates that HP's MediaSmart Server was destined to receive in the not-too-distant future? Yeah, well apparently, every other WHS device on the block will also be receiving those upgrades via Power Pack 1. However, Microsoft didn't go any further than saying that they'd be available sometime this spring through Windows Update. Huzzah?
