The passive changes for heavy armor will take place when Dark Brotherhood patch for Xbox is released ... regardless of whether you crafted new heavy armor beforehand or didn't.
Therefore, the passive changes alone shouldn't hold you up ... if you're interested in crafting the heavy set now.
One other piece of advice:
If you're not totally sure of your build after patch (with the new heavy armor) CRAFT IT IN CP150 (V15) FIRST.
That way, you're not out of a ton of end game rubedite on armor you don't like. Moreover, ZOS could still make heavy armor changes this week on PTS that might swing your build one way or the other ... yet another reason to craft it CP150 if you're doing it before patch.
Bracing:
Renamed this passive ability to Wrath.
Redesigned this passive ability so it now increases your Weapon and Spell Damage by 10/20 for 6 seconds after taking damage at Ranks I/II respectively, stacking up to 10 times.
Constitution: Increased the amount of Magicka and Stamina restored from this passive ability whenever you are hit by approximately 275%.
Juggernaut: Increased the amount of maximum health this passive grants per piece of Heavy Armor to 1/2% at Ranks I/II from 0.5/1%.
Rapid Mending:
This passive ability no longer increments its bonuses with each piece of Heavy Armor, and now requires 5 pieces or more of Heavy Armor to be worn.
Increased the healing taken bonus to 4/8%
This ability now increases the amount of resources your Heavy Attacks restore by 25/50% at Ranks I/II.
