Ask your retailer, they are the account holder and Mizuno updates them with ETA changes. As with most, if not all OEMs they communicate through their retail channels on open orders so lines don't get crossed.
Thnx guys, I did sent a mail to the store and I got a reply the next day that all components should be at Mizuno by the end of that week, so in prob 2 weeks I would get them. Well got them today can't wait to play them this weekend. this means I finally got my bag ready. It ended up being a mix set. Cobra woods (radspeed) Mizuno irons and wedges and a scotty putter ( phantom x 8.5 )
