I'd say Bitmain is going to take a break from all of this bitcoin business for a while and focus on Litecoin
Scrypt is a MUCH smaller market than SHA256 though - even with the recent jump in Litecoin price, and the jumps of a couple of the "much smaller market cap" other Scrypt coins, there is no way the market will be able to asorb 20+ batches of L3+ like the Bitcoin market has managed to soak on S9/R4/T9 batches and still want more.
I stand by my earlier statement - Bitmain is only doing Scrypt miners at this point because
(1) they have very little competiton and NO "close on performance" competition, so they can price the stuff pretty high and make good profits on it while undercutting their ONLY competition
(2) they have finally gotten to the point they have more chip-making capacity available to them on the current node vs how many chips they needed to keep up with their SHA256 miner demand, so they decided to use the excess on SOMETHING rather than letting it go entirely to waste.
