Look its simple. They know most people are going to be able to talk themselves or their wives(remember those?) into two versions of the same character at the most when its this price. When the costume isn't very differant anyway. We know this wasnt to hold us over while they worked on something more complex, as reflected by the poll asking us which we'd like to see next.
So why not release this now, and get the people who aren't sure if they'll make it to something like a ToD version.
Honestly if this was the ToD version, that'd be it for me, I wouldnt even consider a LC or CS Indy no matter how good it looked. Not all of us live in our parents basement, I have to justify to the others living with me, why theres not one, but 2 or 3, 18" Harrison Fords sitting around.
But rather then this, they should have done Mola Ram or Henry Sr. for filler.
Now we may not see another Indy PF period.
