FYI- Although PA on PC has been out for a couple of years, it's not been its complete form. Escape mode and various others weren't added until Dec 2015, far into our development process for consoles. The last (and final) major update for PC was only this month. This is not the same version, it would never have been possible to create the same version.
We are not withholding information to torment you- there has not yet been a decision on Escape Mode. When that decision is made either way, we will let you know.
The last update was indeed the beginning of August, which is three weeks ago. The next one will be coming within the next fortnight, putting our updates at about once a month. These updates are generally bug fixes and Name In The Game intakes and will not contain new content.
