According to sources the half-elf is the multi-classing giant. But from what we know already, they only get a free MC feat that grants a replacement at-will power. Big deal. The human gets a free feat (pick MC) and an extra at-will slot so he can add his MC at-will power to his arsenal rather than replace one of his main class powers with the MC power. Just from that the human will dominate the MC scene.
Any discussion should focus on what we do know now rather than "we don't have the books, it'll change".
