i my opinion this ui looks awesome, kinda similar to bf2. it is community-made, and will be impletmented into the game if it gets enough likes.
here's a video showcasing it
and this is the link you go to if you want to endors/like it so it will be a part of the game! getsatisfaction.com/battlefield3/topics/...3_gui_concept_2_0_pc
i hope you like it as well, because i really want this!
