This is BIG news very big news......
IF anybody not noticed and took me ages to see it. The matchmaking/sync issues most of it was caused by matchmaking in black ops 1/MW3. MW3 is the worse example and on PS3 black ops 1 matchmaking is terrible.
Problem is how the game check for your area and pairs you is iffy.
In past games never used to check for your area
Hopeful this means that matchmaking has improved and we won't get black ops 1 again or MW3. Hopeful and only taken 2 years worth of bitching to change it back.
