Here is another analysis video and IMO probably the best so far. It's on par with GIMR's production and direction wise but overall better since it avoids using any frame data estimates, since that's pretty unreliable at moment. He also points some things that hasn't been pick up on by others.

As far as speculated issue of Sheik interrupting Cloud's Limit use is concerned, I don't think it will be an problem if two conditions are met:
1.) If Limit Breaks can indeed charged by use of Special Moves or attacks as it is looking.
2.) If Blade Beam can clash with Needles as opposed to the later going through.
The result of this would essentially screw up Sheik's Needle game against Cloud and force her to approach his strike zone, right where he would want her. Arguably we probably only need the second condition filled but in any case here on really it's ultimately a battle of reads.
One thing is certain though, this one of those match ups Cloud really doesn't want to be off-stage with this risky recovery. Thankfully with two meteor smashes and our range Cloud shouldn't have to all that much. Heck a well timed LB Blade Beam on the edge of the stage wreck the opposition badly.
