and than gamma????
gamma was said to have no whipe ... is that still correct?
Incorrect. Beta 3 ended Thursday, Nov 20, 2014, Beta 3.9 began on Thursday, Nov 20, 2014. There was a wipe for beta 3.9
On Saturday, Nov 22, 2014, Gamma starts, this is a preview/prerelease. There is reported to be a wipe preceeding it, to kick off Gamma.
On Tuesday, Dec 16, 2014, Elite Dangerous is releasing in it's full release. It is still unknown if there will or will not be a wipe for this. Early reports were that there was to be no wipe for release, another report came in stating that if there were changes to the database, or significant enough changes due to reports from Gamma, there will be a wipe. So this is still up in the air.
I hope this is clear enough, I don't have the links to the above reports, but if you search the forums, you will find them.
wasnt mecenary edition advertised with preorders/backers get an headstart into the game and imideate access to beta?
I read a post by Michael Brookes saying they did not intend Gamma to be a headstart, again, you'll have to search the forums for that.
