Does Layering Affect Queues?

I would really like to get an official response from Blizzard. If they have made an official response, please direct me to it.

Do layers lower the queue for servers? When phase 2 happens and layering is gone, will there suddenly be 30k queues?

I think when it comes to convincing people to do the free realm transfers, Blizzard should be transparent about how they expect the queues to be in phase 2 when it will be far too late to change realms.

According to the blue post they expect expect extreme queues when layering is removed.

You can do your own research, they have talked about layering many many times.

Of course it affects queues, that was the whole point.
