Talk:Mark XLVIII/@comment-35163166-20180528174141/@comment-5846800-20180528224125

The MCU  wikia seems to be saying that the particles are just relocating, but it kind of looks like nano-tech regeneration to me. The suit likely uses nano-tech and Tony might be using the nanoparticles to help him heal his wounds. What I mean it might be using primarely Nano-tech but the nanoparticles are used for biological needs to keep Tony alive.

Anyway

I seem to found something interesting, the wiki dedicated to everything in the MCU are calling the new Hulkbuster the Mark 49, if this is true of course then that would leave the Mark 48. If this is true, which someone in Marvel Studios still need to confirm it, then we still have the mysterious Mark 48. Though I still like to think, like what Xxdd321 said, is that the Mark 48 is a prototype to the Mark 50. Hopefully we see the Mark 48 in Avengers 4, whatever they call the fourth Avengers movie.
