Um... They ALWAYS do at LEAST 2/3 upgrades yearly.
2.0, 2.1, 2.1.2, 3.0, 3.1, 3.1.2, 3.1.3, 3.2, 3.2.2, 4.0
That's MOST LIKELY going to be the pattern.
There is always a x.0 initial upgrade release, followed by the x.1 bug fix release. Then there's the 'screw the jailbreakers' x.1.2 release that's usually put out, etc.
That's pretty much been the pattern since 1.0, dude....
a two-year history is not enough to base the future off of.
and you missed That there were 9 1.x.x releases in the first year and skipped 3.1.1.
That they did those releases means NOTHING for the future.
