I never hear anyone complaining about formerly Nintendo exclusives getting ported over to the competition, which happened with the recent Goldeneye game and with No More Heroes. Those used to be Wii exclusive, but a couple years later they appeared on the PS360 and yet no one gripes about that.
Once again, those are two different audiences, so there is an opportunity to garner new sales. The largely-casual audience on the Wii is
not the same audience as the largely-core audience on the 360/PS3. The Wii U's projected largely-core audience and the 360/PS3's largely-core audience overlap, so there's a smaller audience likely to buy ports of games they can already play for cheaper. And what do those 2 ports you mentioned have in common? New content, as well as new HD visuals to give people a reason to buy them over the original Wii version, which is what I
said needed to be added to such ports. Also, GoldenEye was only a year old when it was ported. That's not as bad as your wanting 6-7 year-old HD ports on the Wii U.
On the other hand, look at RE4 Wii edition which is a port of a game that was on the GC and PS2. This game has sold over a million copies on the Wii alone and is on the list of top 50 selling Wii games. So how could that not be argued a success for Capcom? Granted, not every port is going to sell that well, but this is an example that proves that at least in some cases porting over high profile games can be financially successful.
Oh look, another port of an old game with
new content (Wii pointer controls and the Ada levels) that justifies owning it on a new console. In fact, the new content easily makes it the best version of that game
still (even with the "HD" version on PSN/XBLA). But there are very few games out there as evergreen on sales as Resident Evil, so how many ports do you
really think would see so much new content to justify their price? I don't think even Capcom's done another port like RE4 Wii since.
It should also be noted that Nintendo expanded their audience
dramatically from the GameCube to the Wii, giving Capcom a much larger base of potential customers to buy a Wii version of RE4. Nintendo will
not expand their audience moving from the Wii to the Wii U. If anything, that audience will actually
shrink unless Nintendo has a console-selling casual title they haven't unveiled yet.
