Already out States-wise, coming out today (on Ps2/PSP anyways), Micro Machines V4, finally a proper sequel to V3 and none of this next-gen boringness/micro maniacs bollocks. 
Few multi-player memories compare to Mega Drive Micro Machines 2 (the J-cart- 4 way play without need for a multitap, bloody genius!) and the level featuring “the sponge”. Friendships were permanently scarred over the antics that went on whilst on board “the sponge”.
Already got mine pre-ordered. Codemasters forever!
