Let's not speculate just yet as to for whom the patch is. Cause I suspect it's only for a certain (early) version.
This patch, is probably meant to get the earlier paradox box version up to speed with the download version, which -because it need not go to a printer and distributor- is probably already developed a bit further at the moment. (I can confirm mine is already V1.1 without patching).
This patch might thus then turn the V1.0 box version to V1.1, whilst the Download that is available tomorrow might already be V1.1 from the get-go. This might just be for the early V1.0 steam version, as seen in that one video.
However, this is also part speculation on my part. But I have inquired as to what's up with this patch. I am suspecting this to be the case though. I'll inform you here if I have an answer. Or perhaps Vstep will already point out what the deal is, tomorrow.
Fred.
