I think it's either 5-10 years or never. I am a huge Java user and fan btw, but I am looking to the next 20 years here. Despite much optimization, GC still struggles with memory efficiency and predictable performance in a diversity of scenarios. You have to tune it. I guess you could simplify my comment to two advantages: No GC, and elegantly baking constructs that make programming safer into the language as opposed to things you can opt-in to. While it may be possible to get these things with Java, if it's a lot simpler to get consistent performance, efficient memory use, protection from null pointers, and safe concurrency.. then there may be an opportunity for Swift.
