The K1 has the same dictionary. What is new is the ease of looking up a word, because the K1 could only select a line with its scrollbar but the K2 can select a single word from the page using the joystick.
One of the advantages of how "minor" the K2 upgrade turned out be be is that there is very good backward compatibility. For almost everything a K1 will be "good enough" at least until the K3 comes out.
