So Issue 5 (already under discussion, since Issue 4 is just in “let’s try to get the frickin’ bugs out so we can release it” mode) will include (ta-daaaah) new power sets.
Statesman has (from what I read) indicated that power sets to come include bows, sonics, brawling, pistols, staves, shields and magnetism.
Oooooooh. Fun stuff.
