Delta isn't offering free wifi. DL is offering free entertainment, some via seatback AVOD, some from onboard server via wifi to personal devices.
As for the OP's question, we may see some indication that DL would use these (to supplement A319s/reassign less fuel efficient 319s) on long/thin routes if AVOD is fitted.
