Re: Looks like I won't be getting KitKat any time soon.
"The document also noted that the Android 4.4 update for the Galaxy S3 I9300 was “cancelled due to unresolved problems.”"
Problems that speculation suggests is more about the Samsung bloatware (in particular Touchwiz) than about any inherent problem with Kitkat and the S3. Which shows two more problems that Samsung face with Touchwiz:
1) Will they do the same thing, and mess Tizen up with bloatware, crap customisations, and rubbish apps that you can't remove?
2) Will the be just as enthusiastic to abandon handsets when it suits them, when those handsets can still be bought new?
3) Will they be just as enthusiastic with the network distribution of updates for Tizen, which slows updates down, or even means they never happen because the network operators cannot be bothered?
The orphaning of the S3 is only the latest in a line of similar moves by Samsung. They clearly still don't understand that customer goodwill is fragile, and customer loyalty easily changed.
