So if that happens people will stop buying them altogether since they are saying they are gonna pull the plug on it.
The only people that are buying one are Nintendo die hards that bought every single system and feel they need to continue to do so. Most people are gonna buy the other 2 because of upcoming titles and 3rd party exclusives. Nintendo doesn't matter what they do with the system unless they redesign the thing without the Gamepad and drop the price then they will continue to get blitzed in against their rivals in the market but would that be to big of a risk to take.
I think the damage has been done already and with announcements like Batman Arkham Knight and other games getting announced for both PS4 and XBox1 shows how much damage has been done.
It seems the Wii U was destined for failure the moment it came out with it's gimmicky controller and online service since the PS3 and 360 had a much stronger service anyway. Yes Zelda will get shown and maybe Smash Bros as well as Bayonetta 2 but that's all and lately Nintendos conferences have been very dissapointing so don't expect any major surprises.
With the PS4 and XBox1 battering the Wii U in sales it's future looks very bleak and E3 won't change that.
I have not heard anyone big up the Dead Space games but I did really like the first 2. The first had that sense of tension at times and I just liked the pacing of 2. 3 on the other hand just never got going for me.
To be fair The Last of Us was better than any of the Uncharted stories by a mile. While the stories are solid enough in Uncharted certain games are leagues ahead in terms of storytelling like Metal Gear,Mass Effect,Red Dead Redemption and Bioshock.
If DK can't what chance has Bayonetta 2 got. It's not like it's an household name like Mass Effect or Assassins Creed.
