It is amazed that in the start of this year, we all want to see when bitcoin cross $2000 and now the time has come and in this time, we all want to see when bitcoin come back. But now the price of bitcoin is out of range.
That's why, when you are rich (now ?) ... you can focus on network evolution : ask to demand.
SegWit first, and then, we see.
Honestly, i don't see the point to miners to refuse SegWit ... except if Miners machines have a problem with this (segwit) and only "newest hardware" (and linux encapsuled miner) are compatibles with segwit instructions (so, since 1 year only).
SegWit benefices, it's like compare CSV and ODS formats = 1,5Mb (CRC don't include) vs. 0,3Mb (4x CRC includes + compression)
