If 8-25mm and 100mm do come out, I would have all I need. Ultra-wide to normal 8-25mm range would be so versatile for urban landscape type stuff, it could even replace my 12-100mm as my main lens. And of course macro is another one of my passions so I need something for that.
Of course, I hope the system continues to grow beyond that and realize its full potential. E-M1 II probably won't last forever, for example, so I will probably need a replacement eventually. Given the size advantage of m4/3, they probably should continue to try to appeal to sports/wildlife photographers, and I think they can do better to appeal to street photographers as well (e.g. silent mechanical shutter, Pen-F2 with tilting LCD, 25mm F1.8 II with MF clutch).
