I'm guessing Dan must have some clause that he couldn't build his signature bass shape (the Lakland 44-01/55-01 shape) which he became famous for hence a return to F style basses. The Lakland head stock is a beautiful design and I actually prefer it to Fender's original design but these new D.Lakin head stocks aren't appealing (well to me at least).
I hope to keep my current Lakland for a long time and while I wish Dan well I think I'll hold out on buying any of his new stuff but who knows what he may have up his sleeve a few years down the line?
