publisher of NGNL isn't really as reach as those other series you mentioned (even SAO and NGNL publisher are under same corporation they still operate independently to a certain degree), and NGNL's commercial value would also be lower than others, with the fact that the original series progression now paused due to original author's body status, and the merchandise and promotional value for its first season still haven't be fully explored yet, i think these are the reason now.
