Nintendo recently unified their handheld and console divisions. I think that had a lot to do with having separate accounts. This rumor is more believable than ever.
I'm extremely skeptical of any rumor that Nintendo's suddenly not only bringing them together but also not taking an easy opportunity to make you buy a game twice for 2 different platforms (see: Nintendo charging you to play your Wii Virtual Console games outside Wii Mode on the Wii U).
Oh, this again. I disagree. Not that I'm against it, but I try to fair. First, Nintendo isn't making anyone buy anything. You do that on your own volition. Second, just because you buy a game on Console A doesn't mean you're entitled to it on Console B. We all go through this every generation. Nothing is stopping you from playing the game on the platform you originally bought it on. Third, you're paying for extra functionality and convenience while Nintendo offers the transfer to Wii U at a discount with the transfer from Wii to Wii U Wii Mode being free. Nintendo didn't have to do either. If you want to take this even further, should we not have had to pay for VC games if we still own the original cartridge? We all want a good bargain, but where does it end?
"But Steam lets me X, Y, and Z." Good for Steam and good on Valve for instituting that. I think it's great, personally. I would love for Nintendo to do the same. I understand why people don't want to pay for a game twice or pay extra in general, but that's nothing more than blatant consumerism. Being admittedly cheap as ****, I'm all about consumerism and savings and whatnot, but it has its limits. If you keep following that path, eventually you're going to want almost everything free all the time forever.
