Maybe some of Walther's people has gotten into Athearn's corperation...
The only thing new recently in HO was a GP15, and a GP7 is following.
Perhaps the N-scale crowd should bug them for SW1000s, SW1500s, and SD40-2s. All models available in HO.
I think you can count Athearn out for the count in 2010, maybe 2011 will be better. It's now nearly September and there's 3 months until Christmas.
If they announce it anything this year, it won't be out till the end of next years. SO if they announce anything in 2011, it'll probably be available in 2012.
Speaking from experience, I had to wait 2 years for my F45, one from the time the first run was announced, the other from the time the BN was announced and it showed up at my doorstep (and I pre-ordered too)
