I will always buy Nintendo's systems; they're the most talented and creative company with the best IPs, IMHO. So the question is whether or not Sony and Microsoft can impress me enough to want their consoles.
This gen, owning one of the HD systems was crucial for me but next gen could be a different story, as none of Microsoft's or Sony's first party games alone warrants me buying an entire system for (except perhaps for the Uncharted series, which I do love).
