This is my official prediction of the major Neo information which will be dropped on Wednesday. This guess is much more of a pipe dream wish than probability, but here goes:
The price will be $449.99 USD and it will release in Mid-November (say the 18th). The major title which will be released alongside the console and will receive "special" Neo treatment will be Red Dead 3. Rockstar still owes Sony an exclusive from the Agent debacle, and I think this will finally be their compromise. While it will release on the One and standard PS4 as well, the resolution and framerate will be demonstrably superior on the Neo version.
