Extra Units if you Pre-Order?

[Gobalopper]

Just found this post over at AVault. It seems those that pre-order Emperor will be able to get three extra units:

Westwood Studios has announced that gamers who pre-purchase their real-time strategic release, Emperor: Battle for Dune, will be given three additional units for use during online matches. Those who pre-purchase the product will be given a special code to access the units -- one for each side -- on Westwood Online. According to press materials, the units will give users "a distinct advantage" during online games. Hmmm...

That seems a little unfair if they give people "a distinct advantage" and it doesn't mention if the code will be given to those who have already pre-ordered or where you have to pre-order from. My guess is that even if this is true people who don't pre-order will find some way to access the units, especially if the access code is the same.
