Future Android OS Updates For The S5

[Greg C]

With Android 4.4.3 starting to emerge it's obviously going to be an incremental update. Will Samsung push the update when it's available or will they bypass it and wait for the next major Android update? How many Android OS updates does Samsung release for their flagship phones such as the S5? Is it usually just one major update? I'm coming from the Nexus 4 so updates were quick and frequent straight from Google.
