The New Scientist article says that the corporation Colossal sequenced the complete genome of the Dire Wolf and will release it to the public.
Whether the puppies match this genome will determine if they are Dire Wolves.
The article notes, Dire Wolf and Grey Wolf havent had a common ancestor in 6 million years. That would imply significant genetic developments even if "99.5%" of the DNA is identical.
"It all comes down to how you define species". But if the DNA proves to be the same (within the genetic diversity of the species) then it is the same species.
