Well, technically Zelda just came out too. Phantom Hourglass, remember? Also, Spirit Tracks was announced. Now, maybe you don't want to have Zelda on the DS, but Zelda has gotten 2 games in the timespan that Mario (main series) has gotten one.
Also, why complain? Nintendo have completely different teams on their different franchises. Mario being released isn't "instead" of anything else. The Zelda team are separate, as are lots of other teams. It makes no sense to be angry about a new Mario coming.
