Most implies greater than 50%. That is mathematically impossible, because 50% of PS2 sales will be 60 Million Wii's (I am simplifying and ignoring households with multiple units of the same console), but that would leave no room for the expanded audience that the Wii has attracted, or for the Gamecube only owners that I am sure have upgraded to Wii. If those people account for 60% of the 60 Million Wii's sold (an educated guess), then only 24 Million former PS2 owners have bought a Wii, and if 50% of those are multi-console owners this generation, then only 12 Million former PS2 owners have become exclusive Wii owners. That would be 10% of them, and not most of them. I'd say more of the former PS2 owners have migrated to XBox360 or PS3 exclusively (I'd guess 15-20% to the former and around 25% to the latter). About 15% likely have gotten a multi-console setup this generation, with most of those including a Wii in there. The remainder (32%) have either stayed with the PS2 only due to finaces, or are out of gaming altogether.
