Suzuka is gone bud...and as for Spa how many times has it been raced in its native configuration or raced at all...its been butchered with movable chicanes and remake of the bus stop...
as for the new plain tracks, I disagree, Turkey is got that quad left turn, Bahrain is shit, so's the Germans (but only 1 this season), Sepang is good cause it has Spa like weather (unpredictable)...and China is good cause MS won last time
....
I think these tracks need more time, however i don't agree with them replacing the the 'good' courses that u've mentioned...
