No, there will not be that kind of an update for Lightroom 4.4. Development on Lightroom 4 has ended. You can download DNG converter 8.7 and create digital negative copies that you can use in Lightroom 4.4. But you will have to upgrade to Lightroom 5 in order to get support for the native raw images.
I kind of expected that answer - it is a shame that Photoshop CS6 gets a free update but I have to spend $79 for a Lightroom upgrade to support a new camera.
DNG is not an option, it makes the workflow more complex.
I don't know why you feel it makes things more complex. All you need to do is use the DNG converter as your download software. The conversion takes place during the download, and then you can import directly into Lightroom. I'm not trying to sell you on using DNG. But it isn't as cumbersome as it seems.
Since Lightroom doesn't utilize the Camera Raw plug-in, it makes it more difficult to provide updates. In Lightroom update means distributing a whole new Lightroom program.
I use a third party program to download, rename and organize the raw files so the DNG conversion would be an extra step and a time consuming one too. I'd rather sort through and delete some of the raw files before doing any conversion. DNG is a good idea in principle, it just not supported everywhere yet.
