I think it's a clever move to made it in 100% CGI. We could get awesome angles and actions. I think another 5 yrs down the road it's hardly could differentiate cgi and real life but by then cgi will use as more of artistic impressions. Only blizzard would made 2hrs movie of their cgis , pure cash galore for them not to mention the stories were wonderful as well. IMO Transformers should be made into CGI rather than life action so that we could see more robots interactions rather than puny humans. CGI Megan Fox anyone!
