I LOVED the last CSI crossover. It was the TV highlight of the year for me. So glad to hear they’re going to be doing it again. I hope it lives up to expectations!
I think a yearly cross over would be cool to carry on, I do like how different the different cities CSIs are though. Vegas is by far my favourite; even if it’s not been the same since Grissom left
