TMNT Shellraiser has two versions?

I was browsing Bricklink when I came upon something very odd in the TMNT section. Apparently two versions of 79104 The Shellraiser Street Chase exist. There is a train base version: http://alpha.bricklink.com/pages/clone/catalogitem.page?S=79104-2#T=S&O={}

There is also a Technic base version: http://alpha.bricklink.com/pages/clone/catalogitem.page?S=79104-3#T=S&O={}

Now I know the Technic version is the second edition of the set because it says so on the catalog description. I assume that I own the Train Base version because my set has train wheels on the underside of the Shellraiser. I'm guessing that Lego made the updated version after all the reviews of the set back in 2013 mentioned that the Shellraiser is very fragile, and most thought the set was bad because of it.

This is the first I'm hearing of a revision, I never heard about this here or on the TMNT forums. A Google search turned up nothing. Does anyone know more about this revised set and want to share? Does anyone own the revised edition?

Interesting, there's a 37 piece difference. This is really cool, but very odd too.

Maybe they made two versions as one was to make the build sturdier. As I bought the set when it initially came out, I can say that it was not a very sturdy build. When something fell off, everything was bound to fall off too. Don't know if it was improved it though.
