For those interested in Enotria: The Last Song, Jyamma Games has released a statement to the Italian media. This is the english translation (ignore any errors if there are any, I’m Italian too 
)
"Jyamma Games officially apologizes to all Xbox players. We are well aware that the news of the lack of presence on Xbox on day one is causing many discussions on the matter and we want to clarify some aspects of the matter with this official statement.
We have been internally discussing the simultaneous release on all platforms for some time, I’m sorry to have communicated it only now, but it is a choice that was made recently and I was officially informed that releasing it on all platforms would have entailed a decline in the general quality of the product as well as a further delay of the same.
I want you to know that the delay caused by the launch on the same date as one of our competitors gave us the opportunity to take more time to further improve the product, this led to raising the bar and I, as CEO, am responsible for the final quality of the product.
That said, I would never allow our game to release discreetly on all platforms, I prefer the game to be perfect on 2 platforms rather than discreet on 3. Once we have released the game we will also get to work on the Xbox version and the DLC, so that we can also give the game to Microsoft users.
The choice fell on PS5 rather than Xbox simply because we have a relationship with our partners in Asia (SEGA) with whom we have agreements that we want to respect as a matter of respect for them. As you may all know, the Asian market is largely dominated by PlayStation, so PS5 was the most logical choice.
However, I would like to clarify some things, Jyamma Games is an independent software house that has never been financed by anyone, including Microsoft, some accusations that have been made by some users are bordering on a lawsuit regarding this issue. I hope that everything is clearer now and that the Xbox community doesn’t get angry about my forced choice."
