For the following scenario, which way would I shift my demand curve and what would be the determinant of demand?

"The price of computers will increase two months from now;- how will this affect the demand for computers?"

1. Demand would decrease and shift would move to the left. The determinant would be the tastes of consumers.
2. Demand would increase and shift would move to the right. The determinant would be the expectations of consumers.
3. Demand would increase and shift would move to the right. The determinant would be the price of related goods or services.
4. None of the above
