I have watched all three of these movies, and I have to say, I was expecting the ending to be Andy giving them to his kids later on down the road. But the ending that was there was worth it too--after all, what more do toys want then to be played with? I cried at the end, it was incredibly touching, a lot like most of the Disney and Pixar movies are. It was in true Disney and Pixar style.
And knowing Woody and the gang, they'll likely have more adventures with the new kid. I was tempted to bring out my Woody and Buzz that I've had since the first movie and watch it with them just like old times when I would sit down to watch the original movie with them.
But toys do not always get ripped and rusty when they are not used for a long time. My mom has a lot of stuffed animals and old Barbie dolls that I used to play with that are old, but none of them are ripped--they were all perfectly intact when I first pulled them out to play with. They might get ripped more easily, yes, but if they're stored in a place that doesn't get moths or anything like that, then they'll be fine. You just have to be a bit more careful with them then you would new toys.
I will add that I think Buzz's "Spanish mode" was hilarious. I nearly died laughing almost the entire time during the "Spanish mode". It made me wonder if he had any other modes. I could imagine a "Russian mode" making him cross his arms and kick his feet in front of him in a Russian dance. Or an "Irish mode" making him do a jig with an Irish accent.
And I agree that Lotso definitely got what he deserved. Just like the Prospector in the second one, nothing really bad happened to him, but he got what was coming to him.
As to making a fourth one... I doubt they will, not after Andy leaving. I think they mean to leave it off at that. If they do make a fourth one, it would rather disappoint me, because it should be left here and not continue any further.
