Seems like so many in here are more interested in just having the latest version of Android and not with what actual improvements might come with it. Being that upgrade paths for the i537 aren't exactly simple (compared to previous phones I had that did not have locked bootloaders) could someone perhaps give us a rundown of what's new and improved in 4.4.2 to make it worth the trouble of upgrading? I am on rooted stock 4.2 with a ton of frozen system apps and before I go through the trouble to get the OTA I would like to assess if it is worth it. Also, will I first have to get the OTA of 4.3 before I will get the 4.4.2 update and if I do should I just wait to root until I have the latest version? Thank you!
You will have to flash the ML2 Odin package to be able to get the OTA for NC9 to install. Personally I would wait a couple weeks since it seems like they're getting very close to unlocking the bootloader.
To answer your question about the 4.4.2 update, I've posted the changelogs from both AT&T and Samsung in this thread
. If you really want a rundown of what the 4.4.2 update will look like, just look at the regular S4. There are slight UI changes between the S4 and S4A, but you'll get the overall impression.
