Tech Toys CR question

We want to show that announcing the new product will hurt sales of the old one. The new product can't hurt the old one's sales unless consumers know about it. If the media announces the new product, more people will know about it and more people will stop buying the old one and wait for the new one.

B says the media will announce it. that means more people will be aware and more people will wait. That strengthens the contention that the manufacturer should wait.

The specific assumption is that people will hear the announcement that the new product is coming.

hey guys...
why not D?..the analyst is pointing out that the consumers are more towards the new technology, and D is directly hitting the premise. Its saying that most of the consumers are likely to buy the new technologies. So why not D?.. Can any1 of u please clarify?

D does not say "most" consumers like new products; it simply says some buy regularly and some don't. We have no idea which group is larger or even whether the statement covers the entire universe of potential buyers. The statement would hold if 1% bought one or two a year and another 1% bought more often.

Remember, "some", in formal logic terms, only means "at least one". D also doesn't reference whether the technologies they buy are new or not, so it can't help us.
