Just because they merged doesnt mean they have to keep it the name, it depends who the majority share holder is, for example when White Star Line merged with Cunard they became Cunard White Star, until Cunard bought all White Star Line share's so they effectively didnt have any say at all and vanished into cunard, Cunard then changed it name back to Cunard, and got rid of its competitor and all there assets. Squaresofts betetr, and you never know what the future has in store.
