TES fans and COD fans don't tend to be the same people. However, Zelda: Skyward Sword is also a major release, it's a fantasy game with more or less medieval themes, releasing only 9 days after Skyrim. I realize that the RPG audience and the Zelda audience differ a bit, but still, these games will definitely cut into each others' sales, being so similar in theme and setting. I'm confident that the end result will be Zelda getting totally overshadowed by Skyrim, which is sort of a shame because it's been in the works for so long, but they did it to themselves. Skyrim's release date had been long established when Nintendo chose 11-20-11 for Zelda.
Unfortunately for Wii owners Skyward Sword is going to be the last game that matters for this console.
Wii hasn't seen an AAA title since last year's Fall,and Zelda will be the last game of this console.
Most Wii owners keep them in the corner collecting dust. I think that a part of them have already forget about Wii and is looking for Wii U from now and on,while another part of them will just pick it to own the last game of the console.
But it's highly possible that Nintendo will release a Wii U port of S.S. shortly after Wii U is out.
I also have a Wii and I like Zelda games,but I'm playing Skyrim first and by the time I get bored of Skyrim, Mass Effect 3 will already be out so I will jump at it.
Probably I might some time get S.S. if I find it at a lower price one or two years after it came out.
Skyrim just has more dungeons,larger world,more quests,better A.I.,graphics,music,and the list goes on...
I've been following Zelda since Ocarina of Time,but this time....
