Final Fantasy VII Remake was announced long before it should is how many fans feel about it. Interesting enough Nomura the director of FF7R and Kingdom Hearts 3 agrees. Coming from the Italian website Multiplayer translated by Dualshockers.com Nomura said it was announced to soon but they had to do it.
“I am aware that we announced it very early, but in the industry, word was starting to spread that we were working on the game, so we decided to stop keeping it a secret and to reveal it officially.”
Another reason is t stop rumor or get ahead of leaks which is more current as companies do more outsourcing.
To be fair I remember hearing about the remake becoming a real game the same day it was announced but before it was revealed on Sony stage. I will post the link form Siliconera.com to show it. Also the same logic applies to KH3 as well according to Nomura.
