Tag, I get a little more jealous every time you post that picture....
As far as t-tops in the future, I'm sure it will happen....right after I buy a convertible. That happened with the 3rd door/4th door thing on my old Silverado...."no, there are no plans to put a 4th door on the extended cab version" (says GM and the dealership)...so I buy a '99 Extended Cab (3 door)....the 2000 models come out with all 4 doors.....DOH!
I'm not sure how the tops would look trying to keep the reverse mohawk look (although, if they'd use "body panels" rather than "glass panels", you should be able to keep the lines), but we've all seen that the reverse mohawk option goes away if you want a sunroof. Meaning, there is a flat roof already tooled and set to go. Start from there to put the t-tops in.
Okay, I know, it isn't happening, quit bitchin'....and I will....but, someone has to keep putting the bug in GM's ear if it's ever going to happen. Like I said before, even the lack of t-tops is still not a deal breaker for me.
