Thanks for the heads up.
I have good memories of playing the original Elite, and was really looking forward to playing Elite Dangerous when it was first announced. However, Braben then broke his promise to provide a DRM free version that didn't require an internet connection. Sadly, that was a deal-breaker for me, so I never bothered buying it.
I generally don't touch any software that has DRM with a bargepole, and I'm presuming that this "free" version will still have some type of DRM embedded in it. However, if it's not going to cost me any money, I might make an exception in this case.
