Buttons are not the problem. Smartphone games cater to a group of gamer, that only partially overlap with gamers on handheld consoles. Main point here is the price of games (not buttons). With 1$/€ per sale you cannot fund big budget. Yes, some games sell extraordinarily well, but that are exceptions, and you cannot plan that. the number of COD-gamers will not substantially increase on smartphones. So the revenue is smaller, hence the game-budgets are smaller for smartphones, leading to a different kind of games.
If companies can start to sell games at the Appstores for at least 20 $/€ (and I mean at sustainable numbers), then handheld consoles get into trouble.
