Only had half an hour, but quickly tested a few Samus things with my 1.1.4 3DS and 1.1.5 3DS. Just copied my post to the Samus boards here...

I think that thing about Fsmash is false. It still whiffs on characters virtually on top of you and walking (however, it's not like it's a problem that holds Samus back in competitive play, there are/were other reasons for that. How people can use this as a way to say Samus is bad is laughable).
Secondly, Jab 1 to Jab 2 apparently linking better is false. It is still the same as before. It used to true combo at 45ish% and it still is. No earlier or later than in 1.1.4. It still helps if you can hit them with the jab close up to get the follow up. Maybe that's what caused a lot of placebo, people not realizing that hitting with the fist launches opponents too far away for a follow up.
Another thing I saw floating about according to ESAM was a change about Bombs. He claimed they came out faster. This is untrue, as they come out and end at the same time. I don't have twitter, but for those who do, it might be a good idea to call ESAM out on that and the jab thing (which he also said was changed) to prevent placebo from being spread -

ESAM did mention that you also get more mobility out of a Bomb in the air. That I was unable to test due to the limited time I had. However, it could be to do with Samus's increased air speed, giving the illusion they provide more distance.
Which brings me to a couple of re-confirmations; yes, it seems fall, fast fall and air speed has been increased. I dunno how to test gravity yet, but I assume that is also changed too.
Grabs indeed have less endlag, all of them, by a small amount (something like 4-6 frames).
Another thing I found is that Dsmash has less endlag, by just a few frames or so. I didn't get chance to test power to see if the knockback was buffed, but I'll come back and confirm that later. Even so, less endlag makes it a bit safer.
