Hmm for some reason, I can easily pre-order the Metal Build / Metal Composite lines from a plethora of local retailers without any worry of them being unable to secure stock.
Adding on to that fact, the pre-order prices over here is almost equal or lower to the MSRP.
This is totally not the case with the Frontier Valks though, where almost none of said retailers offer pre-orders b/c they are unable to guarantee the stock (and even if they did offer, it usually costs at least >50SGD over the MSRP).
¯\_(ツ)_/¯
