That's good advice. Look for price competition - and sometimes vastly better routings that bigger stations can offer.

The answer for the OP's question on Business class pricing is unknown - and unknowable. Nobody - and no airline - can predict pricing with high accuracy for travel ten months away on routings with ten or more possible carriers (even limiting things to sensible two-segment and time-efficient itineraries). OP should look for sensible routing & pricing combo today, buy that if it appeals, and not look back. No buyer's remorse.
