Amazing how they were  able to keep the outfit on Thor for about 43 years and now are gonna change it. I mean people like batman got a style change pretty  quick, same goes for ironman etc.

 It is amazing.  I think on Iron Man thou, they considered the 'Grey' armor to scary so they very quickly changed it to Gold.  Then it was Ditko who gave him the slick Red & Gold Armor that he would keep for about 20 years.  I think with Thor, Kirby had been playing around with the idea for nearly 20 years before presenting him, so he kind of had a head start - we just didn't get to see the changes.  Batman on the other hand, seems to fluctuate between his original scary 'Batman' to the somewhat less scary (let's hope the campy watered down version never returns.)

well we've had this one too...
 

I was always ok with thor's costume but i prefer his helmet from the movie just because the dish bowl look just seemed cheesy 

It's classic Thor for a reason.. it's classic.  :)

That's 70 years.. not almost 100.  ;)  Another 30 years is a long time.
