Ooof, three separate Links would awful though. lol
LoZ's got all these cool characters that could potentially be new reps for the series in smash; characters such as Classic blue pig Ganon with his trident, Midna riding on a wolf, Impa (Skyward Sword version hopefully), Skull Kid, Ghirahim, Urbosa, etc.
I really don't wanna see any of the characters lose out to yet another Link.
I feel like what they're gonna do is just modernize Link with a few new BotW-inspired moves (hold A for the flurry rush, ancient arrow shot for the full bow charge, remote controlled bomb runes, hold jump for glider, maybe a spear thrust for the Side B, etc.), but ultimately keep the iconic play-style intact.
