October 2015 is soonest we will see SA2015. No factory can deliver prior.
Three items to note-
1 sa2010 will be good with most sanctions until October 2020
2. Most mfg's recommend replacement after 5 years use
3 there will likely be significant cost increase in SA2015 due to all helmets must come with m6 inserts similar to SAH 2010
I will post more about SA2015 as it comes available.
To answer a few questions that have been asked- please refer here-
