I very much doubt that Blood Angels/Space Wolves/Orks(or any army) will ever see codex specific powers ever again. Through the years, GW has centralized more and more rules to the main rulebook.. which makes updates a lot easier. Also, if you look at the Grey Knight FAQs, most psyker units have very specific
Santic powers( they don't roll on the chart, they just automatically know them). This leads me to beleive that this will be exactly how it will be worded when the new codex eventually comes out. This is also the reason I think Ork players shouldn't hold their breath for "Gork/Mork" powers when the new book is released.
However fear not, I assume Ork psykers are cheap.. and they really don't care about blowing up anyways. Tis the Orky way
