Check MMB and see the Wiki here to see what configuration type of 777 your on then post back here? Also, when is your flight? If it's ages away it could be changed again!
There's also the Seating Queries - Club World thread but there are many posts in here re best seats etc
Old style really isn't that bad and its a fairly 'short' long haul your on.
Ignore Seatguru completely.
