GRAW 3 and Rainbow Six Vegas 3 secretly unveiled at Ubidays 2008?

Tom Clancy's GRAW 3 teaser
Something you might’ve missed on the Ubidays 2008 event back on May 28th was the below “10 Years of Tom Clancy Games” trailer. Not only does it briefly show past games, it also touts hints at unannounced upcoming Tom Clancy games with the line: “The Future Will Be Explosive.” The CGI footage shows Rainbow Six: Vegas 3, GRAW 3 (Ghost Recon Advanced Warfighter 3), Splinter Cell (Conviction?), and HAWX (High Altitude Warfare Experimental Squadron).

After 10 years of best-selling games, what’s next? Watch this Tom Clancy trailer to see for yourself.

As part of Ubisoft’s earnings report a month ago, the developer mentioned it had a pair of unannounced sequels in existing franchises set for release by the end of March 2009.

With Ubisoft not having announced their E3 2008 lineup yet, could this be part of their unveilings come July 15?
