The NES version is quirky, as your link points out. It's best described as an 8-sided die, with rolls for 8 or the previous piece triggering a single reroll. The probability of the next piece being an "I" do not increase after a long drought.
Newer versions of Tetris give random permutations drawn from a 7-tetrominoe bag, so the longest possible drought between two "I" pieces is 12 tetrominoes.
