I've also heard there'll be an XTC advanced in 2013 (not sure if it would be an SL model) - very keenly awaiting to learn what the specs and prices will be.I've been informed that the 2013 model will be an XTC advanced Sl model, rather than the composite the current model uses.
I hope this happens, because I'm depending on it
As for Giant warranties - I cracked by anthem frame last Sunday, in the shop on Monday, Giant got me a new frame by Friday.
