CNN: Debris field discovered near sub search area.

9. A debris field implies it broke up somehow...

But a pressure implosion wouldn't do that. A section would blow in and pressure would instantly equalize.

Even if you assume the air rushing out would break something off, it doesn't equate to a field. One or two larger pieces and a few small at most.

They must have video though. It should be pretty conclusive.
