9. Console Price Drops
This year's E3 is an unlikely venue for console manufacturers to announce price drops to their existing consoles. Given the recent leak that Microsoft was planning to announce a new subscription-based service for the Xbox 360, we're not likely to see any actual price drop for the actual console, as it would undermine their plans for the service.
Likewise, the price of the PlayStation 3 is unlikely to get any lower simply because of how cheap it already is and how well it's been selling in recent months. There's no reason for Sony to take a further hit on its profits.
Finally, the Wii's a little too old—and it costs less than dirt—so Nintendo's unlikely to lower the price any further.
That said, any of these companies might announce a new bundle for their preexisting consoles, but we're unlikely to see any real reduction in prices.
