Hi OneGod3Persons,
Welcome to the forums.
I can understand you wanting to Splinter Cell Conviction again as it is a great game, also one of my favourite in the series along with Blacklist.
However, I'm afraid that we have no updates regarding the Ubisoft+ subscription availability on consoles.
As previously mentioned, we can only recommend that you keep an eye on our official web pages for any future news and updates regarding this.
