I can definitely see where this could become a problem. A lot of the "girl" toys are playing directly into the gender stereotypes to get girls interested. If you want girls to like it, make it pink and put flowers on it. Instead of working to actually make it something that would actually interest girls (or god forbid both boys and girls) they just slap some paint on it and give it a girly name.
The bigger issue though is that they have to make "girl" things because most of them are specifically geared towards boys. That is why the answer they come up with is to make it girly. There is no reason we need special Legos in a pink box with cats and houses specifically for girls. Just stop specifically targeting boys with your marketing and girls will want to play with it (see the ads from the 70s that have both genders in the ads). More stereotypes are not the answer to the current stereotypes.
