Speculation about upcoming Sony GM lens refreshes: Is the 100-400mm GM next?

Since everyone is always speculating about what Sony will release next, I’ve put together a small table. With the Olympic Games coming up, the 100–400mm and the 400mm look like strong candidates for a “GM II” version. Especially the 100–400mm, which Sony promoted heavily for sports photography. Of course, an update to the 24mm would also be interesting…

On average, GM lenses are replaced every 6.5 years. What do you hope to get next?
