I'd put Nintendo either level or slightly ahead of Sony, with Microsoft slightly ahead of that.
The key is with heavy-hitting titles. Microsoft wins with the Halo overload, as Sony and Nintendo's headliners (Uncharted and Zelda) were too sparse and too far out.
I'd say Nintendo has the strongest lineup for 2014 as a first party, however.

Monster Hunter: pissing me off since 2010.
