X-ray has had the same timeframe of release of their new chassis' for years now. I'm sure they know what they are doing. For those that feel they need a new car now can opt to get what ever chassis manufacturer that they please. But I'm sure good thing come to those who wait. Regardless they always seem to sell out once released so rushing to debut their t4 is not an option for them. I've owned the t1, t2, and now the t3. Most like will own a t4 because I'm sure it'll be a great car. I've also owned associated and hot bodies too but alway returned to the X-ray due to quality, reliability and consistency of X-ray.
