Pre-ordered the game today.
It's probably one of the best investments you will make. Not only does the game come with a UDK, but years of support from TWI, a large community and some really awesome mods in the works. It's basically a game that keeps on giving.
All of the updates to RO1 made the game last so long. The new vehicles, maps, ect.
Hopefully RO2 will be similar. I want to try making maps, but I'll see if I get the time...
In RO2 related news, "relaxed realism" is now referred to as "standard". I am going to guess most of the new players will stick with standard thinking it is the main game mode (perhaps it is...). They will probably view realism as the "hardcore" modes of BFBC2 and CoD. There is a sticky on their forums regarding the differences between the two modes.
