Considering we're debuting our 3rd new game in 4 expos, I think we can safely drop the 3-4 years gag now. Maybe you can tell us another "our next game is The Sound of Music" joke too?
I just looked it up, and aside from some very preliminary work being done around expo 2015, programming on DI didn't start in earnest until June 1, 2016. Version 1.0 was release on May 5, 2017, and 1.13 (the one the vast majority shipped with) released on June 1, 2017, exactly a year later. Just so we're clear on the facts we're throwing around.
The comparisons are not as far off as you think.
We're getting better and will keep getting better.
