Not true, there's a repecharge so the third placed teams from a couple of pools will end up qualifying for the QFs.
No have a look at the draw,

47 19/10/2007 3rd/4th Paris
48 20/10/2007 Final St Denis
So no 3rd place teams make the quarters, the 4 pool winners and 4 runners up make it. Its the same as 2003. In 1999 they had 5 pools and the best third place team made the playoffs for the quarter finals with the 5 runners up, the 3 winners of those playoffs went through with the 5 pool winner to the quarters. Perhaps your getting confused with 1999.
Also a few people have France, Argentina and ireland all making the QFs, its not possible.
