I logged into my developer blog today (although we have had a couple of reports of sightings prior to this) to discover a message waiting for me which shows that Microsoft are starting to really push the linked Windows Live IDs that came in last October. This shows that some of the big changes we're expecting around People (and Photos) are starting to see the light of day:
So this fits in with the time frame we expect for Wave 3, so will make it interesting to see what other changes they will be making to the content of Live Spaces users as well as the other services (think: What’s New feed).
