the funny thing is that in some countries when you buy a new house the only ETA is x months after the government gives all the permits or a certain amount of lots are sold.
maybe they should have an ETA page that is fixed to "exactly 1 month" from now and you can see the estimate going up second by second. A continuously updating eta, what more could people ask for.
I extend the time allocated for every ETA I give by one day whenever someone asks for an ETA on a project I'm working on or complains that it's taking too long. Currently, this sets the ETA for 1.7 packs to the end of September, in 2018...
