EURUSD, Euro should surge if GDP is positive

What fundamentals could move Euro? Fridays (12:00 PM) GDP Growth Rate YoY, forecast 0.74%, previous 0.8%
What fundamentals could move USD? Fridays (03:30 PM) Retail Sales YoY, forecast 4.8%, previous 4.3%

A. Euro should surge if GDP is positive, it should surge even more if US retail sails is not good.
B. Vise verse if GDP is negative, it should plunge, it should plunge even more if US retail sails is good.

What story we will see tomorrow? Somehow I think A have chance. No?
