>>28621092Use a little fucking common sense - the earlier they release the demo, the bigger the gap between the demo and release, and the more the hype subsides. Getting a demo out 2-3 weeks before a big release is usually optimal, so unless they do a slow roll out like the ORAS demo, mid to late October is the only logical window.
It has nothing to do with industry standards or being different, it's about using the hype to sell games.
