When will the next generation of Litcoin Miners be available?

I’m wondering if anyone has any ideas or information about when the next generation of ASICs will come on the market. Does anyone know?

Looks like the A4+ and L3+ are the best available miners at the moment.

i feel like the companies that make them will use them until next spring, then ship them all out, then come up with something new for the next fall eff us all over.
