I am looking at getting into m43rds. I am going to get the nice 12-35/35-100mm f2.8s. I would also like to get something at the longer end. I saw a rumours/roadmap about a 2.8 150mm which might be tempting but I would prefer a long zoom. Given normal product cycles and rumors, do people think Panasonic will have a replacement for their 100-300mm in the next ~6 months?
