No feature specifics available yet, but history tells us that OPPO's players tend to have all outputs active simultaneously unless there's a good reason it can't happen (no SACD output over coaxial/optical due to licensing restrictions being the classic "good reason it can't happen").
As discussed in the past, the cost savings to drop SACD and DVD-Audio is also very, very small. They would use the same System-on-Chip either way, and likely the same loader. There's no difference in hardware cost. Once the firmware is written and the licensing fees paid, it's all done.
Players can use the same video processor without using the same components elsewhere in the signal path. It's unlikely that LG's problems with that player would carry over to the BDP-93.
