Wait a few more days and you will have more options. If you like it or not. 😉
But in general it is about your preferences. For myself I do not want to go wider as 30mm on the S2. Even if a 24mm on the S2 is interesting. But if you like to have something wider. Wait for the 24. You could also get rid of the 35 and 70 to buy the 30-90mm.
More options make life more complicated. :p
