Ok, even though I said I would watch it tomorrow, I JUST finished it (skipped the whole memory rubbish, literally the exact same stuff as the SAO episodes...)
The last 8 seconds of it give you a small (SMALL) glimpse to the next series.
Even though you knew it was bound to happen half way through. =l
Best bit is in the last 20 mins or so though IMO.
