There won't be a demo. Demos mean less sales for all games, regardless of how amazingly good they are. Hence very few demos lately.
A very odd set of rules are involved here and I'm quoting from published metrics.
Demos are expensive, and have four cases:
Still buying: I was going to buy the game, played the demo, and am still going to buy the game. No change for the company.
Now buying: I wasn't going to buy the game, but after the demo, I will. +1 for the company but quite rare as those not buying aren't motivated to play or 'enjoy' the demo. They want their preconceptions to be confirmed and look for negatives however tentative.
Not buying: I was going to buy the game, but the demo didn't fulfil all of my desires. I'm not buying now. -1 for the company
Never buying: I wasn't going to buy the game, and the demo didn't change my mind or I didn't test it. No change for the company.
Unfortunately for people who like demos, the "Now buying" group tends to be outnumbered by the "Not buying" group; which means that many companies see demos as spending money to lose customers.
Now, we leave all marketing and commercial decisions to Bandai Namco but the data is in and it's clear. Demos, regardless of how good the game is, cost money and do nothing for sales.
Keep this between us.
Half of this was nicked from Reddit after I recalled reading it there and in two other places.
