Nothing about being on high horses. Simple way to say it, been 10 years, its on a 12 year old console. You can only keep things alive on outdated things for so long before they become a hindrance. People can upgrade, and if they are gamers should have upgraded by now. By the end of the next 2 years we should see a new gen on consoles, meaning the PS2 will be 2 gens behind. Games for it are mostly not sold in stores, the console is dying and it is generally time to move on, FFXI is probably the only game still even alive on PS2.
I love the PS2, I got it when it came out and played it for 9 years as my only system I ever really played, then I went to Xbox 360 around 3 years ago, I still play PS2 but I accept the system is old and dying, and I expect nothing good to come of this game keeping it around. If they were to say now that FFXI will be alive for 5 more years, I would expect them to drop all PS2s in the next year or 2 then move on and possible support another console when releasing a pack with all the expansions.
