Yea, it's kind of weird how they promised 2 new algos, but all of a sudden, they release a new miner with exactly only 2 algos and is ready to be shipped in just 7 days.
So I am guessing that they have this miner/algo for awhile and decided to mine the 2 new algos themselves until profits go down hill and thought maybe, "Hey, we can just put 2 new algos on a new miner and sell it as a whole new machine for more money".
Because if they release 2 new algos for x10 miners through an update, they make no more money.
Baikal sure is all about greed.
