I'll be the downer and say that even if this WAS exactly what we hope it is, it almost certainly won't lead to "warp drives" of any kind. Not directly, anyway.
The problem with the Alcubierre engine is that we still don't know of any way to prevent particles from becoming trapped in the forward and rear bubbles. To be blunt, we would still have no way of operating these engines without potentially projecting these fantastically energized particles behind (not so bad) or ahead of (SERIOUSLY bad) the craft using this engine.
...and that's even assuming we can prevent additional mass from impacting the bubbles in transit, which would have as-yet unknown consequences. Even if we can make a warp bubble, the Alcubierre engine is still a non-starter until we solve other, much more difficult problems.
