Yup the menu system is a dead give away...like Bhruic said. Add to that comments by Epic or CliffyBS about how the PC version & development....
UT99 is one of my fav games of all time..but 2k7 seems to be the last real UT game. I do not expect any future version to be released to the PC.
Wonder if CLiffyBS & DSmart are related?
PS. UT3 sucks compared to previous versions but when it comes to recent games..it's the best Deathmatch option. CoD4 DM ...well ...worst spawn sytem I've ever seen. (kill..turn back..&back track & run into the same guy 90% of the tme don't do it & he'll get you from behind no vaseline)
