I'd keep checking daily to try and get some good seats reserved earlier, but if all else fails there's always OLCI that opens up 48h prior to departure.

P.S. Are the "premium seats" in exit rows available or taken? This might be a good way to change your seats early to something more preferable. The fee is quite small and you get infinite leg room in return.
