Is the Lego Duplo Track System being discontinued?
It hasn't been officially announced yet, but there are at least four large LEGO DUPLO train sets coming this summer. This includes two extension train track packs with straight tracks, curved tracks, switches, bridges, and train crossings. The two full train sets will include more of the same tracks. The set numbers for the extension packs are #10872 and #10882, and the new train sets are #10874 and #10875. The official set names are prices are yet unknown. I would suggest to wait until the summer, unless you can get the older sets for a very good price.
