To me, the face that Chaz, Griffin and TerencetheTractor525 suggested is the best one

My predictions:

HO Scale:
Stepney

Narrow Gauge:
Sir Handel

  I really liked the new Bachmann announcement. I think LBSC Thomas and Busy Bee James will be great additions to the HO scale line.
  The announcement of N scale James really caught me by surprise. I didn't expect Bachmann to reveal a brand new engine for this line now.
  It's great that Bachmann is making Diesel for the Large scale line. I think he really fits the line.

HO Scale
Stepney or Ryan

Narrow Gauge
Sir Handel
Brake Van

N Scale
James

I think Stepney is a better option than Ryan because he is a classic character. However, since Daisy was announced Ryan would also be a good option.

I don't understand why bachmann not yet revealed the Oliver model?

I wanted to have Skarloey in my hands but it is very expensive to import to my country.
