Jaf, it's not a technical issue. The $149 upgrade is a special price, it's simply not available during the pre-release period, just like a sale price is not always available. We decided to have a pre-release because we were getting so much interest in trying TG3 early, but if you can't pay the $199 price (or you just don't need the render nodes), the final release is just a couple weeks away. We certainly appreciate your patience.
