Rumors say it might be, but yeah, no substance to them yet. But the fact that the price dropped so fast is a very, very bad sign... this definitely looks like one of the best games of the year and for it to be so cheap so fast it must have sold awfully. :(
Don't listen to the rumors, it hasn't been discontinued! It just sold very poorly, which means that there probably won't be a sequel which it so desperately deserves.
I think I'm going to jump off a bridge now.
... well okay, so it's just a little bridge at a playground, but it's the thought that counts, right? Right? ...
