The last music / talk event regarding NieR took place on March 20, 2012. It was purely a lottery drawing in which 200 lucky people were able to attend. Saito Yosuke has previously stated how nice it would be to put on something similar again, but this time, it would probably have to be a paid event. He has also put out feelers via a poll on Twitter to see exactly how many people would be willing to pay.
“Regarding that NieR thing, too… just a bit longer, just a bit longer…”
ニーアのアレも、もう少し、もう少し…
