I agree that the change now would not be big, but on the other hand, why not make the best they can make now instead of waiting for a big upgrade
Because developing and marketing a new camera when the majority of its target consumer is still satisfied with the older model doesnt make sense. Like I said earlier, the E3 is not exactly a camera for those interested in much of the gimmicky features that would separate the E3 from its successor. As an E3 owner, if the successor were released today, it would not have enough features for me to consider upgrading.
It would be a great camera, and would sell, this is not up for questioning; however, if the marketing and development costs where routed towards an even better camera somewhere further down the line, the profits would be much higher.
Entry level cameras are high volume sellers and for those it makes sense to always facelift and push new models quickly. Professional level cameras are much smaller volume sellers, and pushing a new camera when so few will be upgrading just doesnt make fiscal sense.
I understand that for an E3 owner it would not be very attractive to upgrade, but many will do it anyway.
For new customers however, I think the E3 needs to be upgraded as soon as possible to make it up to date with the competition. This should no be a big effort for them. If they combine what they already have you would get a camera with:
- 12 MP
- ISO 6400 (better high iso)
- better contrast based AF
- movie mode (for those who like it)
- hdmi connection
- maybe faster
Probably I forget something, but this is already enough to justify an upgrade.
