They're saying nothing at all other then that ED as it stands won't work with the 0.7 SDK.
As usual, they are playing their cards very close to their chests and as usual this gives massive room for interpretation which leads to rumour which leads to speculation which leads to a lot of nonsense spouted on these forums.
With that in mind, my reading of the above is that it is very much expectation management from FD. The more cynical among you will see this as confirmation that they won't be making any effort to implement further SDKs prior to the launch of CV1 or that they will be dropping rift support in favour of [insert your preferred device here] at the earliest opportunity.
The more pragmatic of you will say that they are just doing the right thing and informing us that the new promised land of 0.7 is not attainable in ED thereby saving a few brave souls the effort of finding this out for themselves; and that they will work in support for 0.7 'when they get a couple of minutes' ('cos they haven't ruled it out', right?).
TBH, whilst I have to hand it to FD in that they have delivered a brilliant VR experience thus far and have gone a long way beyond what could be expected to support a bunch of early adopters playing with a dev kit, I find what isn't said in the announcement above troubling. NDAs notwithstanding, they've given us no real news other than a vague statement that they 'might' be doing 'something' at some unspecified point in the future. This is frustrating as hell and leads to irritation that they can't come out and give us some real answers with a real timeline.
That said, I managed a couple of hours of play last night and seem to have found a sweet spot on my rig which works pretty much perfectly, so until the consumer-ready devices come out what do I care?
