Hello,
As there is very less official news on the web regarding HOW the EWS implementation will be done. As per the news and what HRD Minister told to Lok Sabha there will be an increase of 5100 seats in IITs and 4500 seats in NITs in coming sessions. However, there has been an increase of around 1309 seats in NITs, 609 in IITs and 209 in IIITs this session to satisfy immediate EWS requirements.
You can take a look at the JoSAA 2019 article here https://engineering.careers360.com/articles/josaa to check the exact increase in seats and other new things in JoSAA counselling 2019.
