I get it... But it's just a bit of a bummer. To have held a standard license since before Steam (I believe we called it full back then)... And your best option is to go for the 135 newcomer like a first time buyer... Since you'd be at 109 to upgrade and then 30 to get unlimited if you bought the upgrade now, in advance of the KS.
Not that I mind paying the 135 - I will... I've been using the product since it was released and don't mind supporting SmiteWorks... Just seems like something could be considered for long time standard holders that want to upgrade in support of the Unity release.
