^ There will definitely be some delays. The sections to Toulouse and to
Hendaye are on hold. There should be some announcements about that pretty soon, from that socialist government that everybody over here is plainly hating. The line to Toulouse is supposed to be upheld, so is the section to
Dax, but further to Hendaye (which is certainly part of the line to Bilbao) might well be badly delayed.
As for the Paris-Bordeaux line, the section between Paris and
Tours is yet an actual LGV. So a (pretty long) section between Tours and Bordeaux is currently upgraded.
That's what's up to the French side. They say that in spite of some budget cuts, the work is already on in the Spanish Basque Country.
This from Wiki seems actually up to date.
