All Nippon Airways Mileage Club - When will seat map be loaded?

We have flight from SFO-NRT in July and it is showing old seat map on website with note saying "your equipment is scheduled to be changed". I've also called and agent sees same thing. When will we ba able to pick seats in the staggered Business cabin?

From what I've read the seatmap is usually updated approx 1 month before the flight.

If you choose a seat now it should carry over when the seatmap changes.
