There's a light at the end of the tunnel! Apparently the new 4-4-0's will be available in November. You can see some photos of them about half-way down this page:

I see they are now listed as "coming soon" with price from $239 - $315. For that much, they better look WAY better than the current models. 
I spoke to the representative and he said the new version isn't ready yet. Aside from supporting DCC, the other good news is that the motor will no longer be in the tender. Apparently there will be a "micro motor" in the locomotive itself which is nice because that eliminates the silly looking plastic drive rod between the cab and tender.
