I think it's all just a dream now of actually getting the 2 new algos. Apparently, they have plenty of time to develop 2 new miners, with total of 7 different algos between the Giant B and Giant N. But have no time to release 2 new algos for the Giant X10.
One route makes them money, other route doesn't.
Actually it is the other way around. The cryptonight algos were supposed to come for the Giant B based on the hidden Scripta pool entries. But they decided to release a new miner instead.
By the way Baikal still has a lot of X10 for sale, and they can sell the surplus only if they make them more attractive for the buyers.
