"Is Nintendo Becoming Lazy?" Hmmm...hard to say. I can see arguments both ways. On the one hand, this is the company that seems extremely fond of giving us extremely safe and by-the-numbers sequels that seem to have the minimal amount of work put into them, like the New Super Mario Bros.; the Wii _____ series; Pilotwings Resort; the N64 ports on 3DS (Ocarina & Star Fox 64) etc. It's the company that decided that making a 4th named character in New Super Mario Bros. Wii and NSMB U was too much work, so they just palette-swapped another Toad character.
But on the other hand, I just got a 3DS and before I stopped to type this I was playing Super Mario 3D Land for the first time and it is anything but lazy. It feels fresh and new with things I haven't seen before in a 3D Mario game, something I far prefer in my Nintendo games than "just how you remember it...only BETTER!" I've also been playing Mario & Luigi 3: Bowser's Inside Story, and that also feels fresh and new within its own series. This is also the company that's making Luigi's Mansion 2, a game I don't think anyone was demanding (however well people look back on that game now, at the time people were really down on that game) and which is certainly a riskier venture than just crapping out yet another Mii-based game. And despite NoA's extreme reluctance to bring the games over here, this is the company that published or developed the niche and expensive Operation Rainfall games.
I think Nintendo is the confused servant of two extremely different masters: the investors who always want the Sure Thing with the least Cost, and the developers/core gamers like us who want to push their creativity to create new experiences. Unfortunately, Sure Things are often the ones that make all the money. I really enjoy Nintendo's more creative or ambitious games, but when they probably have 5 times the development cost and 1/5 the financial return of something like a New Super Mario Bros. or Mario Kart game, it's not hard to see why the Investor half usually wins when Nintendo's planning projects. Until people either stop buying the Sure Hits in such ridiculously massive numbers or they start buying the creative games in massive numbers, we're probably not going to see this trend towards "Easy, Sure Hits with Minimal Effort" end.
As for Reggie, I've really never liked him. When he's on stage, I just don't hear the passion one would expect from a guy selling entertainment products. He never sounds like he cares about the games he is talking about. Everything's cold; calculated; condescending; and focus group-tested, conveyed with an extremely slow and dry Shatner-esque delivery. If he can't sound excited by his products, why should I be? And that's not even getting into what games Reggie allows NoA to publish in NA compared to the other regions.
