No information regarding the change of the EWS guidelines is available on internet. So nothing conclusive can be provided. On MEESEVA also the guidelines are the same as before. So you aren't eligible as per the guidelines for the EWS certificate as your family have greater than 5 acres of land.

I would recommend you to contact the SDO/ADM/DM office for more details regarding it. If there are changes then the officials will provide you the information.

Have a great day!
