The proposal to raise the limit regarding ESI & PF is under consideration. So far, no official notification or circular has been issued by the department apart from a statement given by the Hon'ble Labour Minister, Central Government. I suggest that you should keep watch on the respective sites of ESIC and EPFO on a regular basis.
Please find attached the statement published in the newspaper, which is self-explanatory.
