I haven't heard of any change in the shootout itself, but when a shootout will be used is being changed:I'm pretty sure they are adjusting their shootout, while not doing away with it completely. I can't remember the specific change.
Stage 1 (double-elimination) -- still go to a shootout if they are tied at 1 set apiece (races to 4).
Stage 2 (single elimination) -- go to a third race to 4 if tied at 1 set apiece. But if the third set goes to 3-3 in games, a shootout will settle it.
