No new details for this particular issue unfortunately, but here is what we know about the series as a whole so far..
"Technical visionary. Unparalleled engineer. Avenger. Iron Man has done it all, from combating the greatest threats facing the Marvel Universe to dealing with his own inner demons. Now, when his greatest invention becomes his greatest mistake, Iron Man must act fact…and build faster! The lethal techno virus Extremis is out in the wild and for grabs to the highest bidder! It’s up to Tony Stark to contain it and that means creating a new suit of armor!"
Kieron Gillen has also revealed a few extra tidbit sin a recent interview, confirming that we can expect to see a lot more than 1 new armor for Stark -
“The story will focus on him questioning things about himself and trying to find out exactly how the universe ticks, what’s this all about and why he does this anyway, There will be a lot of changes in the armor throughout the series; in the first five issues there will be a different armor every issue.”
