Not a year. A year and a half. A year and a half ago they said they would be delayed to...a year ago. So the deadline you refer to is already a delayed one.
This game has been KS'ed in 2013. We are at the door of 2018. So, if we consider the last updates, most European backers will get their stuff...half a decade after the campaign.
And the content the Minecart backers have payed for is already sold to other people. The outlaw pledge as a whole is almost already available in stores for quite a long time. That's completely unacceptable.
If you like to pay before anyone to get your good long after everyone, good for you. Just don't make it look like critics don't apply and complaining is a heresy.
4 years between two waves, it just doesn't make any sense.
