Also, guilty as charged on procrastinating my pre-order of the upgrade at a discount price.
This morning I purchased the upgrade and I noticed that the discount rate didn't apply to my purchase. On closer inspection the eSim store has the full upgraded version of Steel Beasts ProPE already listed. I rushed to the official eSim forums and found this post made yesterday by Ssnake, stating:
Well, actually the packing will take most of the weekend. Shipping will start this Monday.It is very likely the upgrade CD is shipping already for those who pre-ordered.
UPDATE: Tom tells us he received his upgrade copy. See comment below. It's happening. Thanks Tom.
