Not sure I follow...
Are you suggesting that it was premature to compare iOS, Android and Windows 8 because the Blackberry 10 is about to be released, and saying that we wouldn't have done a compare like this if iOS was just about to release a new version of their platform?
The difference there is that one would be Apple releasing an iOS upgrade, and the other is RIM releasing a Blackberry-OS upgrade.
Isn't quite the same thing. One has significant anticipation and high expectations across a huge segment of the population. The other does not.
