Best Buy needs to be the first place to get the newest and coolest tech, period.
For instance, when the Galaxy Note II was released on T-Mobile, I went out the day of release to the nearest T-Mobile store and bought it. I had been waiting for months for it and wanted it as soon as it came out. It has taken a while for any other stores that sell cell phones to have this phone available. If it were available at Best Buy on the same day at the same price, I probably would've gone there to pick it up, but it was not available through BB until weeks, if not months, later.
A lot of people are looking at the new tech being shown off at CES right now. Any of us who are wanting to purchase what we see will have to wait until it is available until we can purchase it. However, if it were to come to BB on the launch date (or even a few days or a week before hand) anyone who can't wait to get their hands on it will come in to buy it. I personally am interested in the Samsung Vacuum Tube Soundbar and am curious as to how it will sound compared to normal soundbars. If BB had one set up in store at release (and advertised such) you would be able to get people in to check it out and purchase it right then if it is available at a competitive price. It would be even better if you could work with some manufacturers (such as Samsung and Sony) to get the products in and available before the official release date.
