Yesterday at the eBay Dev Con someone mentioned a pending big Tuesday announcement at eBay Live.
Given the audience that will be in attendance my money is on the announcement of worldwide integration of Skype Click to Call within the Ebay web portal.
A lot of what I saw this weekend leads me to believe that web based integration this year is a big part of the Skype and eBay ecosystem development. I also feel though that there is also likely some integration that will occur the other way, where information about your eBay auctions and bids will appear inside the Skype browser.
Yes, Skype browser. So much of what they are doing leads me to believe that Skype will be more than just a phone client.
Given the sparse participation of Microsoft at the event after it appeared they would have a bigger role, my gut also says that the reported high level discussions that were going on between eBay and MSFT have stalled, or soured.
For that reason I see more and more relevance that Skype wants more of your desktop and eBay wants you using Skype for more than just text chat and phone calls.
