The site I have looked at say Spring 2008. The stuff is made in China. Maybe the locos are in a container in Los Angeles Port.
Don't forget, the to be released HO Spectrums will not have all the decoder features that come with a stock Tsunami or Micro-Tsunami decoder. but they are acceptable. The sound is very good and very good speed control. I have installed the Micro-Tsunami in my HO steamers including the Richmond 4-4-0.
And search the 'Net before buying any of the new Spectrums. The 4-6-0, 4-4-0, Shay with sound $400 retail. Micro Mark $208. Your mileage may vary.

If you ever fall over in public, pick yourself up and say “sorry it’s been a while since I inhabited a body.” And just walk away.
