It really doesn't bother me either. I'm used to it in SS, but when I play Pearl, I don't notice that it's gone. It was a fun feature, always interesting to see what a certain Pokemon will do or react to in a particular environment, or to see how they even felt about the player character. It gave the Pokemon more of a personality that wasn't in the other games because there were so rare opportunities to see what they were thinking in previous games, but in HG/SS, they were right there to "ask".
That's really what I'm going to miss about the feature if it actually is gone (I'm not making any definite guesses about Black/White). There was more personality for the Pokemon, like my Geodude's wishing of playing with me or how my Slowpoke rolls around in the grass every chance she gets. It was just more fun.
But if it's gone, it's gone. I'll just go back to using my imagination to fill in my team's personality, or maybe the games have another feature that adds to it.
