It is not 39 to 100, it is 80 (discounted price) to 100 (current price) USD, if you do not have SplitEQ. 20 USD more because of missing discount period…
You could buy SplitEQ now for 59 instead of upgrading for 100, and have all plugins that are now in A XII…. But you will miss the surprise that should come for A XII users… IMHO, if you trust, that surprise/plugin will come, it is better to upgrade to A XII now, than to buy SplitEQ, as later conversion to A XII would most probably cost more than 40 USD (it was the discounted price)…
