@ GT_Nagpur....
It would be naive to look at this purely from a 'career boom' perspective...that would be very short term.
What i would suggest is to go ahead with your MBA programme, have a feel of the subjects and the course in general...talk to alums and fellow batchmates (for that matter anyone you can talk to) and once you have settled in the course...take stock of your strengths +interest in subjects + placement scenario in your institute to take a call
I am assuming you would have to choose your electives in the 2nd year of your MBA, so why get jittery over it right now?
Secondly, there is a slight distinction between a System Analyst and working in the IT industry (as a marketing/HR/Ops/Fin) Professional.
Its not an obvious distinction but to give you an example you can be working on business development for an IT firm without taking up a full blooded system specialization.
