My LBS Yeti dealer was saying that the alloy AS-R 5 is no more, but carbon is sticking around. Definitely not a rumor, but reality. I'm glad I liked the 95 more anyway, because I'd be out of luck on my order this past week.
Sounds like you might have been able to pick up a smoking deal on the 5 in a few days,
From reading through this thread and some of the links in here, I have some thoughts.
It wouldn't surprise me if they dropped it as sales probably aren't great, but it would be sad if they discontinued the ARC. I was going to pull the trigger on an XS or S one as the next bike for my daughter as she moves past her 24".
A full carbon Big Top makes sense and I would put money down on one right now.
A disc ARC-X would find its way into my stable if they produced it.
