I would too. It might upset the night landscape users who shoot wide at 2.8, but what's an extra stop. ISO 400 instead of ISO 200 wont be that much noticeable on a 1" sensor. Maybe in very low light situations where ISO 3200 is now pushed to ISO 6400. Fortunately, the IS is usually good enough to be used hand-held at very low shutters, so that could help push the ISO back down for static scenes, but not for action.Given the sensor size, I'd be happy to have a constant f/4.0 600mm lens. That aperture range is next to impossible.This from another site

Now This, if true, is really interesting!! Note the 1.8-2.8 IS lens
- 20.2MP 1" High-Sensitivity CMOS Sensor
- DIGIC 6 Image Processor
- 25x Optical Zoom f/1.8-2.8 IS Lens
- 24-600mm (35mm Equivalent)
- 3.0" 1,040k-Dot Tilting Touchscreen LCD
- High-Speed AF with 31 Focus Points
- Full HD Video Recording at 60p
- ISO 12,800 & 6.5 fps Continuous Shooting
- Control Ring, Dials & Built-In ND Filter
- Built-In Wi-Fi Connectivity with NFC
But for the majority of shooting, f/4 would be the most useful aperture when balancing dof and exposure.
Usually in a zoom system that starts at f/2.8, it gets to f/3.5 quite quickly, so not much difference to f/4.
