Yes, it is absolutely necessary to buy a WiiU if you plan on buying future Nintendo console games.
ok so, i JUST heard about this whole "wii u" thingy, and i'm curious about what it is, just b/c well, i just heard of it, as well as the fact that we just got a brand new wii. i mean is it worth buying?? do i need to buy one?? is there any reason i should?? seriously it doesn't seem necessary to me. thanks.
You're going to need a Wii U because the Wii U is different than the Wii.
(See, this is why Nintendo shouldn't have named it the Wii U)
Anyways, the WiiU is the next new Nintendo console, and is not just an upgraded Wii. It will have plenty of exclusive games that won't play on the Wii. It also has a completely new, amazing controller that the Wii Remote can't even compete with.
It really does look like it's own console. If the 3DS only had a single screen, this design would probably fit the bill perfectly.
And towards your question of whether or not the WiiU is "necessary": until you exhaust your supply of enjoyable Wii games to buy (it could take you awhile, lol), I can't say you'd need to buy a WiiU. A new console should be bought because you want to buy the great new games that come with it, after all.
Hope this answers all of your questions.
Its also a kick to your wallets unmentionables.
Aye, ye speak truth. Cap'n Morgan himself would have t' pay a coffer 'n a half for one. I hanged the jib good when I first saw the price to be 'round $399 dubloons... Hornswagglin' swabs, the bunch of 'em!
