I don´t think so, since the inception of the videogame industry, game budgets went only in one direction up, up and up. I agree with the point that new engines will (probably) streamline the content creating process, but if you want to increase the details (on a character, in the environment etc.)you still need more time to do so... there is a lot of wishful thinking involved ...
...and even the modest and positive estimates made by Guerilla Games and Epic suggested that game budgets would "only" increase by 20%, which is absolutely laughable, 130 people on one game are already far too many (imo)
