I buy the consoles that have enough of the games that I want for it to justify the price of the console. Whether the console fails or succeeds I'll be happy with my purchase since I got it to play those games. The only way sales of the console will affect my purchase is if the console fails to sell enough hardware for developers to make games for said console, thus there won't be enough games I want to justify purchasing it.
For games I usually stick to what I like or games that are getting good previews/reviews, though I may be inclined to check out a game that is selling massive amounts.
