He's absolutely right though. Just because they are making new servers doesn't mean more people will start on yours or any other. In reality, if they know how these games work, they are waiting for a new server. Hence, if none ever show, you lose a massive amount of players, popularity, income, etc...
On the note of server merges they will address the situation when they need to. You and I don't have access to stats telling just how many people log in daily to each server. They will start to merge when they have to but for now the big concern is just having enough content to entertain people. If you look through forums there are threads everywhere asking for this, that and the other while still demanding for new content. I'm sure even you would agree that it would be easier to just fix little things and add new content while adding new servers rather than trying to do all that while merging servers.
Plus, yes, we get quite a few cross server events going forward from what we have seen in other regions.
