So last year, for pre-ordering Destiny, PS3/4 players were promised access to the beta.

Turns out the exclusive beta access is for only 4 days .

Is this a joke ?

What proportion of people having pre-ordered the game might have been mislead/manipulated ?

Oh wow this is gonna end badly

Can always cancel the pre-order and pick it up later for cheap.

Beta these days sometimes just means a demo.

Edit: Good points by posters below. Hmm. 

Does the ad actually mean that? I mean, it says four days exclusive beta access, but does it actually say four days before the game gets released?

You're spinning this out of proportion. This doesn't actually say anything about the context.

These 4 days could be anytime.
It doesn't say if Xbox will get beta or not.
It might as well be that PS gets the beta 4 days earlier than Xbox and it will be for a month.

This could mean anything. It could even be a typo.

LOL, I am not even surprised... Thanks Activision

I think it means that they get a beta for 4 days. Could be long before other platforms get a beta

it means the ps users get the beta for 4 days before the xbox players can get in

mmmh, not sure, the ad was removed so i guess there aren't any more details than this

might be - will update OP
