I think we will have an alt coin season but it will be limited to major altcoins such as ethereum XRP Waves and maybe few more.
But there will be no shit coin season for sure.
Shit coins are gonna die very fast.
What about medium coins? Between the top 100 and shitcoins, there are a lot of assets that will survive. This is a fairly large market share. These coins/tokens will also be pumped. But when will it be? I do not think that in 2019.
