You've still got a few more months there until those games come out, so I wouldn't worry. I'm only really looking forward to a few games, such as Metroid Prime 2: Echoes (they should drop the "2" from the title), and Paper Mario 2. Might be something else as well...

But if all else fails, beg your parents for money. It usually works for me, and remember, assuming you celebrate it, Christmas is just around the corner from all the big games' release dates.
