I think that as this year will be the last with events, they will change the rate of the game next year, in fact they should change now, because a lot of people have already abandoned the game.
It has already been said that officials are being closed when Ark 2 comes out. Cedric has made it very clear in more than one post.
"We are putting all the event items into the HLNA store so you can have a last chance to get them all and so that when Ark 2 is released they will still be available to all the people who play on unofficial servers, which we will be keeping on".
Keeping the unofficials on. Bc pay-per-month. Officials not staying on.
On the plus side, the release of Ark 2 has already been delayed and given the track record of 'major' releases we still have plenty of time left with Ark 1.
Fyi - total time of Gen 2 delay ('delay' being defined as "confirmed date" changing from originally announced date to actual date of release) was only just shy of a year. For a single DLC. G2 was announced just over 2 years before it was finally released - the G2 announcement is still available online if you care that much.
