That's what I mean, $$$ does not solve any problem, if you have need for a tele lens the 25mm is waste of money. That is why I also will get Sigma when the 135-400mm becomes available. However, the 50-200mm would just give me 50mm more than the 45-150mm I already have. Yes, I also have the 14-45mm which includes even the 25mm range but the Leica is f1.4 and that is really something else than f4.5.
On the other hand, if it will cost US$1k I may have to wait for stronger motivation and will to spend that much on one single lens. Then again, I thought the ED50 f2.0 was very expensive too, but ever since I received it, it is on my camera almost all the time except for the three weeks it was in the "Oly hospital". I prefer to take a few steps back instead of using the 14-45mm, so maybe if I had the Leica those two lenses would be THE two most used ones and I would not need tha 14-45 at all.
