Hello there,
Since some of the points COULD happen during the rest of development, I'll focus on the ones that are incorrect or that won't happen.
1. It is highly unlikely for Ken's room or Sam's computer to be added. Sam is mainly considered a "finished" character and at most will receive 1-2 more scenes. For Anna's tablet (not a laptop), is a possibility to happen, but other things have priority.
3. Mario doesn't stay free because of Sofia, but because he is corrupt and has bought ppl on the judicial sector. By the end of this route of the quest, you can even kill him. So, this route extension request doesn't make any sense with the narrative, nor the characters.
11. Tristan's girls are unlikely to receive any content, could happen but is unlikely.
12. The rule of thumb is, the characters more likely to have content are "named" characters, so is really unlikely.
As for the last 2 points, those are added every version, Anna has a new place to be called to, and there are some eastereggs/secret content.
