I think it all depends. If somehow, consoles do have something that make them a must have, than, most likely a high price won`t be a problem. But i just don`t see that happening, not even for Wii U.
Taking into consideration how some european markets will be affected next year, it would be wise to not release them with a high price point. That would not only endanger themselves but also the companies that develop games for it. And if those companies fail, so will the consoles who won`t have that many games or there will be fewer AAA games, making the consoles less significant.
I sincerely don`t have high expectations for next gen consoles with higher prices (which could also mean, more powerfull consoles), specially because of the european market.
