Saw something that said the entire longhaul fleet woild have new seats by end of summer '15.

Is that true for 747-400 fleet too?

We are flying IAD FRA on LH 417 in early June and its shows only C and Y but when I pull up seat map. It shows old config.

Anyone know what we should expect? Its the 3pm ish departure so unlikely to sleep much anyway but would certainly perfer the new seat.

Appreciate any info.
