As the title suggests, Google has rolled out a Flash based version of Google Talk called Gtalkr.
It includes a Yahoo Maps extension – as Google Maps is not Flash based – this is unfortunate because Yahoo Maps is US only 
Gtalkr also includes your Gmail account automatically (you log in using your Gmail credentials), so it looks like Google are trying to make this a home page for users.
I spotted this on TechCrunch – hopefully the Google Talk blog will break the story soon!
UPDATE:
Robin has correctly pointed out to me that the web-based Flash version of Google Talk is not a Google product – in a footnote on the base of the site it clearly says:

Time to get those eyes checked again Tom!

It’s not a google product. See the footnote!!
When I read it, I really didn’t think they’d plug Y maps, and was right!
Ah – well spotted Robin – d’oh!
There is a Flash version of google maps: http://www.flashearth.com/ but its not a google product either
