Did wizards reveal which five planeswalkers will survive...in an alchemy card?

If wizards teased 10 planeswalkers in the set with the threat of half of them getting turned into phyrexians....why did they release a set in Brother's War Alchemy that shows five of those exact ten standing around together heroically? Is it a red herring, or just awkward timing?

They say Koth will make it out ok, but now i'm starting to second guess if there's layers of red herrings or it's (admittedly very likely to be) just a very unfortunately timed coincidence.
