Try again now.
There is loads of info coming out at the moment.
is the starting point of everything, which will lead you to http://windowslivepreview.com/
, which in turn will eventually lead you to http://windowslivepreview.com/messenger/resources
where all the videos are.
If you didn't get enough from that, see http://windowsteamblog.com/blogs/windowslive/arch...ive-messenger.aspx
. Still not enough? See http://www.microsoft.com/presspass/presskits/windowslive/
which is about a keynote Ballmer is giving/gave in Brazil where he talks more about wave4. The actual keynote should be on demand later, but there already is a demo video online. Also, a 14 minute interview on http://channel9.msdn.com/posts/LarryLarsen/New-Wi...Messenger-Preview/
just in case you still didn't have enough. That's all released today, although a lot of things were already known from leaked screenshots.

The Windows Live Wave 4 screenshots are the same M3 of MVP Summit 2010... Not actual version.
So even while all the above became public today, all the screenshots are from a build which existed at least since late February when the MVPs were shown some screenshots. I guess the only exception to that is the Channel9 interview (which shows Messenger runing directly from someone's PC in the Live team, where all the other screenshots and demos are likely made by a PR company). Notice the smaller ads in the build shown in the Channel9 interview.
for interesting wave4 news in general.
As for actually downloading it:
* Supposedly MVPs got access today
* Most likely of all rumors is a limited beta May 18th (relatively small group)
* Public beta June 7th.
...Although nobody is really sure and a lot of people are saying contradicting things. Everbody is just still speculating based on the leaked timeline:
* 28 April VIP testers will get access to latest builds…
* 18 May WL2010 M3 RTW.
* 3 June Complete Public disclosure.
* 7 June Public Beta Day.
* 7 June iPhone main languages Messenger.
* 25 August iPhone additional languages Messenger + PUBLIC RTW
The web services and essentials suite can also be released at separate dates and nothing in the time line says which of the 2 they are talking about.
