[Update 3: JAL has published an updated version of the seat map which you can find in this post]
[Update2: Added explanation from JAL regarding why there are more seats than advertised on the W83 seat map]
[Update: JAL has removed the W83 configuration from their website but the picture is still available. And the booking engine still shows a seat map that matches the one announced earlier today. Did they take it down because of a mistake in the Economy cabin?]
Finally, Japan Airlines (JAL) has set the launch date for the new long-haul Boeing 777-300ER cabins, SKY SUITE 777 (SS7). JAL will first roll out the new SS7 on Tokyo Narita (NRT) - London Heathrow (LHR) route from January 9 2013. But initially it will only be available on odd numbered days in January and even number days in February as JAL will only have one retrofitted SS7 in January. By late February, JAL will have retrofitted 2 SS7s and it will be available on the LHR route on a daily basis.

However, bobbybrown from FlyerTalk pointed out that there are a total of 143 Economy seats on the seat map instead of the advertised 135 seats. In the Japanese version of the SS7 site, JAL puts a remark next to 135 explaining that's the number of seats sold on an international flight.
