The SCG still turns? Hasn't seemed to - anywhere near as much - since about 2002\03 TBH.
And I thought The 'Gabba was supposed to have been a seamer's paradise throughout the 1990s? That's what you always told me when saying Hayden couldn't be a non-seaming-track bully.
TBH, I'd say tracks in India have changed - hugely. You could be almost certain of at least two real, proper turners - quickish, uneven, really offering big turn. Now a whole series can go by without it.
Pitches in West Indies might have started becoming slower and lower in the mid-1990s rather than the early 2000s, true - it's the bowlers rather than the pitches that changed there. The only two that were ever (generally) that quick at any time, though, were Sabina Park and Kensington Oval were they not?
And over here - well, times of play have changed, sure, but if anything you'd expect it to have made things
more seam-friendly, not less - Tests in May and September used to be a never-never and almost-never (respectively) before 2000. Between 2001 and 2006, in domestic FC cricket, there was an absurd explosion in runscoring (though that had as much, IMO, to do with balls as pitches). This was mirrored in Tests from 2002. A seaming deck has been a relative rarity here since then - and IMO a non-seaming deck should be the exception not the rule. These isles are supposed to be about a challenge from seam and swing.
There's been immense disquiet over here, and in India, and finally (it seems) in Australia about flat pitches. Sure, there are a few grounds that've remained the same (The Oval's square in 1976 could be transported 30 years on and it'd be almost the same) but I'm surprised anyone would perport that little has changed.
