COD4 engine running on Wii for COD5?

Im 90% sure that CoD2 has alot of Quake 3 in it as it had the same sound bug that happend occationally in all Q3 based games i have played for a longer amount of time.

CoD2 has custom renderers etc, but lot of the code lying under, scripting etc (actually, pretty much everything else i think?) is Q3 based

Yup. Honestly I think I read somewhere that it was Q3 with added visual capabilities (shaders). The game plays exactly like CoD1, so I see no need for them to have used anything new outside of graphics.
