Reedy 5000 mAh 7.4V Pro LiPo pack

I was looking at purchasing a Ni-Mh charger and some new batterys soon but I stumbled on this. Now that it looks like Li-po will be safer, cheaper and easier to fit in off road cars, does anybody think that Li-po will be accepted into brca rules in the short term and more importantly does anybody think it will it completely take over and make Ni-Mh batteries obsolete in time? Or will people stick with Ni-Mh for years to come? What are peoples views?
