This is correct. Currently BFGminer doesn't support Keccak or Scrypt-N or Scrypt-Jane or whatever new / alternative algorithms.
Please, please I'd ask everyone to contact the developers for these coins and ask them to merge support for these algos into BFGMiner. Both Luke and I welcome this and would love to see support for these in BFGMiner.
At some point I may merge them in myself but I'm super busy as-is, and we'd much prefer that the original authors merge in and maintain their code. Again we definitely welcome it in BFGMiner.
I know some users are already contacting the authors - the more the better.
Gladly, I'll contact them and request bfgminer support.
GPU scrypt mining will be dead soon and VTC is the only hope I see to keep them earning
