Trident V DOlphin

Whats the difference?

Is Trident more for developers or is it an upgraded version of Dolphin?

If Trident is better than Dolphin, is it worth me spending so much time and money developing a number of Dolphin sites or paying for premium membership, only to be outdated when Trident is released???

Please - a little more info??!

Thanks- daihlo

Trident will have some of batter of dolphin functionality! is not next of dolphin version
