Looking at a production schedule posted on the LGB Family forum, the rail sections, tie sections, and rail joiners to make flex track should all be in production. When/if it gets to the US is another question.
It should also be mentioned that a piece of 12" Piko track is 11" long. Someone in our club had a few pieces of it sent to them and they were all this way. Maybe they were cutoffs or rejects (i hope) but they were marked as 12".
LGB and Piko track is made is made in Europe using metric measurements. 300mm often called 1 foot sections actually measures approximately 11 3/4". 600mm measures approximately 23 1/2", and so on. The small pieces of Piko track and ties are being made in two sizes 320mm which is 12.66" and 280mm which is 10.96".
