Harada specifically says Revision + Expansion. Tekken 2 never had an expansion, just a rebalance/revision. Tekken 7 has also been getting balance patches, but no expansion yet. Tekken Tag Tournament 2's expansion did have a subtitle it went from this:
to this:
Console version ignored it, as did Tekken 6 w/ Bloodline Rebellion, as will Tekken 7 whenever that update gets revealed.
EDIT: And whenever that expansion gets revealed, be prepared to wait quite a bit for the console release after. 2017 or at the earliest Holiday 2016 is the most probable outcome.
