Will there be any speculations in this thread?
Lets reason for a moment. Epic is probably not totally satisfied with this game, so there will be another patch. Lots of fine looking custom made content have been released lately. Epic might turn some of that into a mega pack. Epic is a small team and they are paid a lot to work on Gears of War 2, not Unreal Tournament 3. Perhaps the community would be better of with Epic only enjoying themselves with mapping for UT3, like when they released UT. People did like GoW so we are not that out of the loop, but it certainly won't be free of charge and you will probably need an X360 to play it during 2009.
Conclusion is, minor patches are expected and more contents will come, but you, the community, have to do that on your own.
