You really would hope so, I think they were discontinued for that reason and they begun to develop a new one, whether that came pt or not i don't know
I couldn't tell you, i dont have anything to do with rockman personally, but they haven't been to great with warranty claims in the past i believe.
Its just something company's tend to do, come up with ridiculous excuses as to why you aren't viable for warranty
The only company i know of that does discount replacement is Onza
Your best bet with rockman is just to go for one of the stronger frames they make, and you are much less likely to have a problem, some of their stuff is real good quality
