I'm VERY sad that the Vita is stereo only. Uncharted sounds so.. restricted in sound compared to it's console brethren, simply because I can't use virtual surround. I have no freaking idea how anyone could think stereo is better for games.... It's like going deaf in one ear.
It got really annoying whenever Drake would talk, his voice would modulate(?) back and forth between the left and right channel real quickly. I thought it was because I was in a cave but it happened in every environment.
