Unlike other dev houses that don't like to comment on rumors, then again they don't comment on much in the way of setting expectations for their community and or customers.

Dice's Repi via twitter said the following:

Fyi we will not add prone based on anything. You can stop asking now.

Also Joch over at Bash and Slash, via twitter was reporting on a possible increase in performance when using the +fullproc switch in your BC2 short cut.

Repi replied, rather quickly to Jocks post saying that it should be a placebo as that switch does nothing.

While we may not like Repi's replies you have to respect that he and other BC2 devs are at least "setting expectations" with their community and not letting rumors get out of hand and that my friend is refreshing and all we as customers / community members ask.
