No one knows what will happen in a year. Maybe other MMOs would've came out before then and take everyone away from waiting. Maybe the new FFXIV finally takes over as WoW crumbles within.
It's not like it is without worry. RO2 would've been hugely successful if it had come out early enough and on time, but it didn't and ultimately tanked and got over run by many other korean MMOs.
It's like predicting who will run for president in 2016. Everyone says it's going to be Ryan for Republicans now, but by 2016 it probably won't be.
In 1-2 years, LO will finally be released. By then if you guys aren't playing any other MMOs and remember there is such a game called Lime Odyssey that exists, you'll then ponder whether or not to download it.
