Not the public at large. I'm just talking about core gamers. The people that get the ball rolling and spread the word to others.
No, power ISN'T everything. It's a, undeniably, HUGE piece of it, though (in game consoles). Otherwise, there would be no new consoles. Beyond power is
flexibility.
Features would be another one.
Content (amount, variety, etc), yet, another large item.
Availability is a deciding factor, as well.
All these things strike at the core gamer's mind. How many would be swayed by price alone? There is a reason for the term
mass market pricing. It's not used to describe bringing in the "core gamer". Why is that? Could it be because core gamers are less concerned with price,
within reason? No core gamers wants to be teased for having the weaker system with less variety of games, worse multiplatform titles AND weaker looking/performing 1st party titles.
If you know core gamers that enjoy being in that situation, PLEASE speak up.
Personally, I go with which ever console covers the most of those categories. Those emotionally invested don't follow those rules. They might just pick the one thing the side they're emotionally invested in has as the most important thing to them. It still doesn't thwart the buyer's remorse and cognitive dissonance that's surely to follow.
BTW, Blu-ray has been outselling DVD on new releases for a while. If it's not released on Blu-ray, of course it doesn't have the opportunity to sell.
