i dont know if its such a smart move on sonys part, announcing it before its done, which is still a few months away, whilst i cant see nintendo doing it, i can see ms buying second life or someone else + adding it to live (still will take at least a year to get up + running though)
im pretty sure ms realize this is gonna add a new definition to the meaning killer app, thus even though they will be ridiculed for copying, the stakes are to high not to
Considering how much flak Sony got for "copying" Microsoft with everything they did when it came to their current online model i wouldn´t worry. Sony just took a giant step over Microsoft and took it to the next level. Impressive and unexpected, i mean, that must have taken some time, moneyz and effort to get it working.
