So supes is getting a new suit and powers? Are they replacing his other powers, or is he just getting more? I really hope they aren't doing that stupid energy being crap again. Will his new suit be similar? Does anyone know?
Superman, as is, has an excellent powerset. Basic, easy to understand and utilize in a story, powerful enough to get the job done, yet also limited in that this forces Supes to be deliberately creative.
If you give him a powerset that's open, this is likely gonna invite more PIS/CIS, ala Surfer and Thor.
Superman is Superman. They did the one thing that was needed (nixed the outside-underoos); now leave him be. If they're having trouble coming up with new stories, hire new writers.
Of course, if this is a temporary situation, it could be interesting. But definitely: no permanent changes. It didn't work then, it won't work now.
Shinier than a speeding bullet.
In all honesty thought it is a plausible conclusion that he could get more powers. I mean look what happened to H'el after traversing through space near different colored suns and other spatial objects.
