I'm surprised no one has started a thread about this yet. Supposedly it will be announced this Thursday, May 1st. It will have a new 28-100mm F1.8-F2.8 lens and an EVF. Those are significant upgrades. Some people have even speculated that it would have the new curved sensor. But Sony has said that the curved sensor is a lens/sensor pair. So it's a prime lens only configuration right now. That's due on the RX2 this summer. Which is ambitious since it's easier to start small and work up. BSI hasn't made it to APS-C yet. Starting at FF is quite a big leap. If the rumors are true, the RX100M3 sounds like a serious upgrade. I hope the price doesn't get seriously upgraded as well.
