If you have a look at some of the young guns cards, if this is based off the best young player award at each club for 2013 (which appears to be the case) we may see some names like:
Tohu Harris (Storm), Kyle Feldt (Cowboys), Corey Oates (Broncos), David Klemmer (Bulldogs), Korbin Sims (Kinghts), Dylan Walker (Souths), Daniel Toupou (Roosters) as some of the signature cards along with players like Tedesco, Moylan, and Don already confirmed.
I think most players will have signed now. The cards need to be shipped back to China for packaging and then shipped back as the final product. If this to were take a month this would be getting very close to the cards being released in late July/early August id imagine.
