When HQ responded to me they did NOT mention a reduction in quota! No promises but my understanding is 16k per app per user.... Of course it could be reduced but a separation by app is very important. I personally had issues with the new limitation and I am very happy even with 6k! At least I KNOW that I have 6k in the app I want to use even after playing in GSAK or other apps.
Anyways, some people simply can't be happy for others it seems...
