I don't know either, and prior to VH it had been limited to TCG pets. But a wave of VH hit in May/June, and of course they reappeared in this most recent wave as well. Here's a post on the May/June wave: http://us.battle.net/wow/en/forum/topic/12673459161
It's possible the TCG pets got hit first because they were the most profitable, and they moved on to other pets after the TCG pet prices tanked. This would fit with the chronology of duping so far -- cub first, 250k+ at the time; then EST, 250k+ at the time; then Dragon Kite, 100k+ at the time; then VH, 120-180k at the time; then Tuskarr/Rocket Chicken/Bananas, roughly 100k/80k/45k at the time. Or maybe it's easier to dupe TCG pets, but VH was so expensive that they made a special effort for that one.
We can only guess at how the dupes get made, so we can only speculate about what might get hit next. Darkmoon Rabbit/Hippogryph Hatchling would be the next logical target if they're going for the most profitable pets -- these are the only remaining non-duped pets that sell for >20k on high-pop servers.
