On Jan. 18, tech giant Microsoft announced plans to acquire Activision Blizzard Inc. for $68.7 billion in a deal that would include smash-hit franchises such as Call of Duty, Warcraft and Candy Crush.

Later that same month, Sony acquired game studio Bungie, creators of first-person shooter Overwatch and the original studio behind Halo, in a deal worth $3.6 billion.

Both acquisitions are significant in their own way, but some in the industry are now wondering where such expansionist moves leave Japanese rival Nintendo?
