I'm curious -- I'm not a video person (at all) but I always find post-market 'upgrades' like the 7D1's firmware upgrade as a chance to breathe energy into a brand. Mid-cycle of a product, legit upgrades like this make sense to signal the brand will still be around for a while / a refresh isn't coming soon.
But to do it within the first year might imply two very different things:
Just curious why Canon wouldn't have this at launch but they are offering/unlocking it now.
- It wasn't ready at time of launch but now they've got it working well and feel comfortable offering it.
- It may have always been working on the camera but it was locked out in firmware to protect higher brand-level camera prices. Perhaps enough people complained that feature wasn't included / Canon underestimated the necessity of that feature such that Canon felt the need to unlock it.
In the past, Canon upgraded video capabilities because professional broadcast people were willing to buy large numbers of cameras if the features were added. I suspect that this time, Canon marketing is trying to prevent broadcasters from purchasing a different brand. The MK IV while not selling poorly, is not wildly successful either, and the tough climate for camera sales probably induces Canon to provide more features if they boost sales.
Not every broadcaster needs a expensive camera and $50,000 lens. I'd suspect that there is a large market for local television stations, for example. There is really no need for a high end camera to do interviews, or videos of traffic accidents, or even produce local commercials where the cost is a huge factor.
