Tangent Scale Models
A few corrections to your market analysis are in order.
First, Tangent Scale Models nor Intermountain released a B&O M53. You are thinking of another brand: Exactrail.
Second, you left out the Tangent Scale Models General American 6,000 Gallon 3-compartment tankcar from your list of styrene pre-war models produced within the past three years. While it is currently sold out (with a new production planned for summer), you can see it here: http://www.tangentscalemodels.com/product-category/sold-out/soldout-generalamerican6000gal3comptankcar/
Finally, I can assure you that Tangent has more up its sleeve for this era, but of course we need more time.

Considering how few new mass production pre-war models have been released in the past few years, compared to so many post-war STMFC and modern era cars, some of us are quite happy with Lee's priorities.
Only 6 newly tooled, high volume production, pre-WWII cars have hit the market in the last 3 years that I can recall - the Fox Valley, Tangent, and IM B&O M53's, the IM offset hopper, the Rapido reefer, the Bowser H30, the Tangent 52'6" Bethlehem Gon, and sort-of on BLI's NYC box car (came with post-war details/roof?). In retrospect, actually a pretty good result for WWII modelers, although I think the NYC box was by far the biggest fleet, and it showed up configured post-war. Sigh...
(I think I spotted 2 more in the previous 2 years - the IM War emergency boxcar and the Accurail 41' gon.)
Many manufacturers seem to be working the post war fleet hard, yet everyone in this group can use the 8 pre-war cars above, so I hope no one is discouraging Lee from focusing on pre-war cars. There are some pretty significant pre-war fleets that are still only available in resin, and being significant fleets, building a bunch of resin kits for an adequate representation can be pretty time consuming.
BTW, I did notice the the B&O class W-2 quad offset hopper showed up in BLI's latest YouTube "sneak peek at the 2014 catalog" video.
