I will describe the 4Tu relation and tell you how it seems to encompass pretty much everything known about sl_2 Khovanov homology: the original theory, tangles and cobordisms, the Lee variant, the Asaeda-Przytycki-Sikora variant and a new variant which works only over Z/2.

Of course, the newly released Khovanov-Rozansky homology is more exciting. But I don't understand it in the least.
