I agree it seems like the T9 thread has been very quiet which really does imply that it addresses the S9/R4 issues. No one complaining yet so this is a good sign. But then again when the S9 first started shipping people were happy too.
So maybe another 30 days and we should probably have a good idea if there is going to be any fallout.
my S9's started failing 80 days in (10 days short of the warranty expiring), got a few boards repaired under warranty. At least now they come with 180 days warranty.
