I usually agree with your posts, but not this time. The TASM2 suit is essentially Raimi's suit with tweaks. It even uses the exact same brick pattern.
I originally agreed with you on them just jumping to a new design with no transition but that was before I saw the other set photos I just linked. If you take a look at those, you'll notice that a lot of the elements from the original suit remain. Elements such as:
-the black webbing (it only looks silver in the first photo released due to the lighting)
-the spider on the back
-the red area around the waist
-the design of the arms (same amount of red and blue as in the first suit)
-the spider on the chest still seems to have the back legs going down to his stomach (though the pic is a bit too blurry)
-the amount of red on the stomach and blue on the waists seems to have remained the same.
Thus it is a blend of the first suit with the suit from the comics/Raimi suit.
