It's not particularly random. Apple supported the iPad 1, iPhone, and iPhone 3G with 2 major software updates + all minors within those major releases. That pattern is now breaking because Apple has continued to sell the iPad 2 and iPhone 3GS for much longer than those other products were available. A more interesting argument might be: given the technical constraints of the 3GS and the fact that it continued to be sold until September 2012, will Apple support it in iOS 7? It seems unlikely, but maybe we'll all be pleasantly surprised. Certainly their choice to go downmarket by selling the 2 previous models has forced them to support those devices for longer timeframes than they may have originally envisioned.
