Well if Wii Sports Resort isn't big budget, what's your objection to them making another?
Who says I object? I certainly don't.
I just don't think that a Wii Sports title is going to have nearly the same impact on Wii U as it did on Wii. The first Wii Sports introduced the masses to Nintendo's vision of active motion controls. Resort shipped bundled with a controller add-on that promised the type of precision people had originally expected from the wiimote. Wii Sports games were the perfect vehicle for Nintendo's new interface and aimed at just the right crowd. The Wii U, however, is a completely different console - with a different focus and primary control interface that doesn't focus on the same level of movement that makes sports mini-games shine.
Of course Nintendo's making another Wii Sports title. But I think expecting it to do exactly for the Wii U what it did for the Wii is naive thinking. In fact, I'll go on record right now and say that I'll be pretty damn surprised if the next Wii Sports sells even half what Resort did.
