Sega has revealed it will not be exhibiting its games at this year's trade and consumer show in Cologne.
The publisher attributed this "commercial decision" to unfortunate timing of its triple-A releases.
Sega's 2012 releases due in the second half of the year include London 2012: The Official Games of the Olympic Games, Sonic & All-Stars Racing Transformed and the long-awaited Aliens: Colonial Marines.
"Sega has made the decision not to attend Gamescom this year," the publisher said in an official statement.
"Gamescom 2011 was a very successful show for us and continues to be the most important European event in the calendar. Unfortunately the release timing of our 2012 triple-A titles and new projects don't work with the mid-August scheduling of the show.
"The decision will not mean that Sega will never attend Gamescom in the future. This was simply a commercial decision made for 2012."
Gamescom 2012 once again takes place in Cologne's Koelnmesse. It kicks off on August 15th and runs until August 19th.
