Craig recently announced the TWag v2 (an improved cable from the original TWag).
The announcement was on head-fi (http://www.head-fi.org/forum/thread/528926/introducing-twag-v2).
He stated that the Overmold cables would only be available in 8 weeks.
I think it would be better to ask Craig about this, and inform all who ordered their cable to prevent occurrences of people wanting to trade-up (refer to above link).
Sorry if this would offend you, but I thought it would be better to inform the guys here, seeing as there are already 2 Singaporeans asking Craig for a trade-up (above link).
