No, from a customer service and a business perspective that would be a HORRIBLE thing to do. Too many servers will ruin you - each server is extremely expensive to maintain every month, if you have extra servers at launch, you are going to pay for those extra servers for the lifetime of the game, even when their population has gotten low and the gameplay on the server is suffering. Unless you piss everybody off by forcing them to switch servers, splitting everyone up from their guildmates or just random people they party with now and then.
And what is happening now, has happened with EVERY big MMO. Every single one has had login issues the first week. It may leave a really bad picture with a few people, but the number of people who would cancel over this issue is a piddling amount in the big picture.
