It's been a while since this question was asked (as far as I'm aware, please don't grill me if it hasn't), but I was wondering if there would be any chance of an -ER coming to the 777, since the -LRs are being phased out in many airlines (Example being BA, who have three, G-ZZZA, G-ZZZB and G-ZZZC, which are to be replaced by -300ERs) and the -ERs are still going strong, so this would be a valued update to the 777 line of products.
