Query about ABAP future in SAP HANA

Hello Experts,

I have read many articles and SDN post about SAP HANA but does not get clear answer.

I am having 7 years of experience of SAP ABAP and wanted to learn ABAP in SAP HANA.

I learn that SAP HANA is having its own language also as SQL script in earlier release but would this be using also in current and future.

So would learning of SQL script give more advantage and how can i get started learning ABAP in SAP HANA.

Thanks

SHiv
