Yeah, I hear the 2016 run of 4750's has arrived or will be arriving soon.
MBK just listed 147 different Intermountain hoppers on their webpage with their NEW flag, which usually means in stock. But today it means out of stock I guess, as none had inventory numbers and you could not order any. Maybe these were the 2016 run you referred to, or some other IM vaporware that hasn't crossed the big pond yet from China.
I was hopeful it was product for a company that seems to need some to sell, but that disappointment gave way to frustration over MBK not being able to settle on way to tag future releases in a consistent and logical manner. Scrolling through pages of not yet in stock items is a waste of time from a vendor that doesn't do pre orders. It would be different if I could reserve a few cars with them. This trend is especially used for Athearn, and it may wind up leading to me giving up on their website altogether as I ordered of Lombard on Friday and the package arrived today. Chicago to central VA over the weekend is not bad for USPS.
