People should stop whining about that.
Apple stated it a while a go that it's the new AppStore policy.Idem with iWork and pages and all.
Now apps are all the price of upgrade and voilà. That's it.
I read that comment many hundred times and can't understand how people can continue to ask for this. It's a 200$ upgrade already.
Also, a few persons mentionned contacting apple and received a refund for logic 9 when bought within a few months of logic X release.
So that's totally fair.
Cubase 750$ and pro-tools 699$ that is unfair, I'd own them too if I could afford it.
