A good idea is to look at what will be out soon and focus on that. Once you get solid dates, then that is what matters. To look MONTHS or YEARS ahead of time, is setting oneself up for disappointment.
I am speculating that a key to happiness might be to be 6 to 12 months behind everyone else. Doing this, when you get a game new, it will likely be less than it costs new, and you can happen to then find out what people are REALLY playing, and what REALLY is good.
