I half agree with you - I don't expect Twitter cares that much - the people sharing photos on Twitter via IG will keep doing so, but I wouldn't expect any Twitter based service to replace IG. The two things are used pretty independently (as in I don't see many people just using Instagram to push filtered photos to Twitter).
