Let's not lose sight of one thing -- this doesn't make chip-and-pin less secure than swipe-and-sign, it just makes it no more secure, in the worst case.
It's not just about security though, it's also about liability. Chip-and-pin may have different liability rules than have been established for signatures. If so, then a hacked chip-and-pin system may be no less secure for the consumer, but it may be much more costly.
