Which module has a good scope in future either SAP HANA or SAP BW?

Hi,

I am SAP BO consultant.Currently in the market SAP BI-BO has good demand, but in future( May be after 2 years) SAP HANA has a good demand.

In SAP HANA  SAP R/3 data directly replicate to HANA using Sybase replicate server and  SAP BI sources & Non SAP Data sources  should be transformed to SAP HANA using  BODS.

In BW 7.3 the DS 4.0 was tightly integrated.

Please guide me which module should i learn,  SAP BW 7.3 with BO 4.0 or SAP HANA with BO DS 4.0 & BO 4.0.

Thanks & Regards,

Rajesh.
