I dont think really. At the moment lots of new entries happen through stupid giveaways. It is not like that the "good" players always win there.
Also if you wanted to buy yourself into the beta, ebay and 99€ were always a possible way of entry.
I think allowing the preorder guys in is the right move for the near future. The game is quite hyped at the moment with lots of streams on twitch and youtube. You have to use the momentum you create.
Also, the game needs people who are willing to pay, otherwise nobody will be able to play it ,-).
