As of right now, all I'm missing is the Vita. So far, Sony hasn't shown me enough that warrants a purchase, but I plan to buy it eventually. As a matter of fact, I plan to buy all next-gen consoles.
If Nintendo does Wii U right, however, I may hold out a little longer on the other two. This gen is the only gen that pushed me to want to get all of the consoles.
It's too early to even tell what each company will do. I can't wait 'til E3 this year & next year, and ever other shows in between.









It's the pink elephant here, everyone knows it's there, but we're not supposed to acknowledge it.
