The only things to be considered canon are the individual films because the movies are what came first in both franchises.
Whatever BS I take from the books/games to throw in the RPGs (hive wars, Praetorians, etc.) are a part of the franchise but can't be considered canon until they appear in the source material, in this case the individual film franchises.
Sadly, that does mean the Newborn is real and the Praetorian isn't, but that also means Bataliens aren't real either, so let's be glad for that.
