I wouldn't say twitter must or must not expand the limit, or even if they should or shouldn't, but I would most definitely welcome that change. Sometimes 140 char limits is too limiting and that's the reason for other microblogging platforms like tumblr gaining popularity. Of course, twitter has more important issues at hand like monetization, and it's not very likely expanding limit has high priority.
