I'm always happy that I'm not a steam loco fan.
Kres' 628.4 was announced in Nuremburg in February 2010 I believe. It is already delayed but will hopefully be available soon (that's a model I want).
Tillig's TRAXX locos were announced in Nuremburg this February. They look quite good, could become one of their better models. In many cases Tillig does unneccessary and annoying careless mistakes - even (or especially?) in the for TT so called most important era IV DR. I'm also waiting for Tillig's class 183 (Siemens ES64 U4) announced in Nuremberg, too. But this one will only be available next year.
Nobody really understands why Tillig also annunced a P8. Not only that there are many other locos that could be done and sold well, they also try to compete with Roco. Although Roco's last TT models (maybe besides the 18201) haven't been the biggest and best thing on the planet, Tillig's locos were always worse (especially with THOSE headlights...). And another important fact is that Roco has one year available to cover the market's needs, before Tillig's P8 will hit the stores - I would have chosen another model.
