I read somewhere recently that FIFA are now open to the idea of playing some of the SA World Cup games on artificial surface due to the tournament being on during South Africa winter/rainy season (sorry, cant remember the actual report, I'll try to dig it out)

You'd think that with all the thought process behind choosing a host nation, they'd have copped well before now that the seasons were different.
Also I think Blatter said the only people against atrificial surfaces are people who have never played on them!!! He obviously never spoke to any away team in Dundalk on a Thursday night!!!!
