The Viper's engine updates are using technology that although higher tech, aren't necessarily state-of-the-art. Dual independent-VVT is the latest VVT system I have heard and Direct Injection seems to be the most innovative technology in that department. The Vipe is using proven technology for the most part. Although the engine has received a serious update, it is still related to the LA series from what I understand. Besides, if I could afford a new Viper, I'd probably wait a year anyways just to be safe.
