There was more than a suggestion....there was a definitive statement:
"Participate in the first round private beta test"
Alphas playtest individual sections of the game (combat module, trading module, etc) but when the modules are released as a collective (the beta) £100 should secure first access.....as promised.
If that's not the case, its a little disapointing, but again I ask:
How much longer do we wait after the Alphas get beta ?
It sounds to me as though you don't have to wait long because Beta is starting in the next few weeks.
I do understand that this sudden realisation that Alpha and Beta overlap is a bit confusing. I think everyone who signed up to the Kickstarter thought that there would be an Alpha period which would be finished, done and dusted and then we would move into Beta.
It seems to me (and I may be wrong) that there is still a whole load more functionality to add. Frontier can't add that new functionality into Beta releases because that isn't a Beta. You have to Alpha test things first and they want to keep doing this. So to get the Beta under-way rather than making you wait forever they are overlapping the processes and you can get started with testing the game.
I think perhaps you are now expecting the Beta to be a continuation of Alpha with a larger group and Frontier should just throw out new builds to the larger group, but then it isn't Beta is it? Where is the Alpha testing of the new functionality?
So either they should have
a) moved Beta further down the road
b) overlap the process
c) Discard the premium Beta and move everyone into a larger Alpha pool
It sounds like you are expecting C but I suspect Frontier have had a long internal discussion and gone for B as a kind of half-way house to keep the process of Alpha to Beta in place while getting you started on the game and what you paid for (premium first round beta)
I could be wrong and maybe Frontier have planned this all along in which case I agree that they should have been clearer about it from the start.
