Well, the mission was the top line car for a touch over 2 years. The Mi2 was released in Feb 2004, so not actually all that long ago.
I just think there are a lot of people guessing about what they think might or might not happen, without actually haveing any real knowledge of the situation.
I don't think there is any danger of seeing an updated Mi2 with shocks and chassis. If the factory was going to do that i think you would have seen it a few months ago. I'll be honest and say i thought they would, but it didn't happen.
For sure the day will come when the Mi2 is replaced, and there is a lot of people with ideas about how they feel it should be. My feeling (based on what i have been told by people that do actually know) is that it isn't about to happen soon. Obviously things could change and i could be proven wrong, we'll see.
