It's the same this year as last year. The slow loop is related to the frequency of the radio packets from the OI and that hasn't changed.
Look in main.c where it says
Code:
if(statusflag.NEW_SPI_DATA) /* 26.2 ms loop area */
1/.0262=38.17 loops per second
The new controller gives us more program and data memory (and a few technical differences or "features"), but most everything else is the same.
