Dear Satish,
If you see at the client/customer prospective
ABAP consultants updating with HANA will be added advantage
I insist ABAP guys should explore capabilities of SAP BI. most of future implementation / support projects will be shifting on HANA some time, so there will be good opportunities as well.
The combination of ABAP, BI and HANA are highly in demanded specially at client place.
All the very best.
