I never expected anything anyway, they already did all kinds of things with the 25th, it would be overkill to celebrate anniversaries like that every 5 years. I'd say wait for it's 50th.
Besides, we're getting ZeldaU this year, TPHD in a couple weeks, a Hyrule Warriors port to 3DS and Triforce Heroes released only a couple months ago. That's too much already.
