Wii would still be market leader. You just need to let people try it and you'll understand that whether PS3 is selling same price, higher or lower, it doesn't matter, people just need to try the Wii and they will fall in love for it. On the other hand, if PS3 was priced below or at the same price as the 360, it is garanteed to outsell the 360 because of bluray alone. It would have meant that PS3 was selling at a fraction of what normal bluray players were going for. If PS3 didn't include a blu-ray player, it would have launched in 2005 and at roughly the same price as the 360, and developers wouldn't have included those mandatory install either thanks to blu-ray's slower read.
