Well it's clear this is going to be an empty quarter so if they released a teaser for this quarter then it would show nothing and we would still be in the same boat as now.
Now I think at the end of this month should be the first maxis monthly that might or might not tease a new pack. Which I guess would be the same as quarterly teasers. But we don't really know yet.
That's why the ended teasers because there wouldn't be paid content every quarter.
Grant did say it would be a busy fall so maybe it's just the calm before the storm.
