Project X 7.0 wait time on iron orders

This question is for a moderator.  I was interested in ordering a new set of 712mbs with project x 7.0 shafts.  I had read somewhere that the PX are on back order.  Anyclue how long till Titleist has the PX in stock to start building sets again with these?  I don't really wanna put my order in and have to wait several weeks. I'd appreciate any info.
