Raster calculator expressions - not transferable to 10.1?

Another question! 

I am in the process of updating a bunch of scripts written not by me, that work under arc 9.2, to work under 10.1.  The original author used many raster calculator string expressions that were then executed like:

gp.SingleOutputMapAlgebra_sa(stringExpression, rasterOutput)

If I understand correctly, there is no string expression input based way to do this, in 10.1.  I need to create the equivalent operations with raster objects, as seen here:

Correct?   I want to make sure, before I go reinventing the wheel, that I need to do this.  Thanks!
