I am in agreement regarding skepticism on how effective Falco can execute his plan.I heard he likes bread.
Potentially, but unlike Luigi, Fox, or Sheik, he has little means to actually get in to to do these combos. On characters with good air speed or low fall speed, Falco might not be able to catch them at all for comboing like how Mario, Luigi, and Yoshi can Nair him if he attempts to go for a followup after D-throw or how Kirby, Jigglypuff, Meta Knight, Charizard, and I think even Triple D can jump out. He's basically the character where if he gets in, he's going to do a ton of damage, but he can be camped out by... everyone. Zelda can sit her princess butt at one end of the stage, reflect when she can, and let Falco run in and get hit by Nayru's Love, Sonic, Captain Falcon, and Little Mac speed camp him, and Ganondorf, Charizard, DK, and Bowser just tank his attempts at forcing approaches as his Blaster is more or less inconveniences to everyone compared to Fox which just irritates people and you know that Fox can get away with that since he's so freaking fast or how Mario and Luigi can glide back and forth with Fireballs or how Toon Link confirm with Bombs. Triple D's Gordos are punishing compared to Falco's Blaster. If anything, Samus and Falco are similar in that they can combo really well, but Falco's got the kill power Samus wants while Samus has the projectile game Falco wants (and the mobility too).
Ignore whatever the hell the intro to this is: https://www.youtube.com/watch?v=dhLiHG_Npi0, but you're not likely going to see Falco pulling these combos off against good DI or the fact he might not even get a chance to do anything since he gets overwhelmed so easily. Maybe less so with how Nair functions now and Fair seemingly being faster, but Falco is really sluggish when the momentum is against him.
But I really like that Falco has a plan now--there's an underlining, overarching point to Smash 4 Falco now, and it seems fun.
