各位高手，目前本人正在做一个关于market entry strategy analysis的报告，其中有一点是关于销售预测的，内容如下：

3. Project sales
Please project total sales for the M-box in Vietnam. Over each of the coming three years, incorporate these estimated retail price points in your projections.
Base system: s30
Accessories:
1. extra controllers: S30
2. Online access kit: S50
3. DVD player kit: S40
4. Monthly rate for online multiplayer capability: S10/mo
NOTE: give projections in both U.S. dollars and the local currency based on current exchange rates (many free web-based currency converters are available)

6. Marketing campaign
Please outline a marketing campaign for launching the M-box in Vietnam. Estimate an appropriate marketing budget and sketch an advertising campaign aimed at the target market you defined earlier. Also, what media does your team recommend for marketing the M-box, and why?


由于本人不是经济学或此相关专业毕业，毕竟还是比较生疏，望高手指条明路，先得预测出未来三年每年消费人数对么？然后下面的配件售价有单价也有全套，那是不是以为着计算的时候不仅仅是算购买全套的销售预测，还得计算每部分零件的销售预测呢？还有怎么预测适合的市场预算呢？很急的，一定得救救同胞呀~在这里先谢过了~
