I bought and beat battle network 3. I loved it. Especially the different styles concept. I'm gonna buy gregar soon and I wanted to know if there are different styles again. (other than the beast out thing)

Well, the style change concept changed. In better words, no more style change. Though a similar idea is in MMBN6. It's a Double Soul. The Gregar and Falzar versions both have different double souls to initiate. It's a bit different from the previous battle network (MMBN5), which you had to sacrafice a chip to initiate a certain double soul. Though you can just select one and it'll last the entire battle, unlike the previous which only lasted three turns. And there is a beast out option. You can go into normal beast out, but you can combine the beast out with the double souls to gain extra powers. Personally, I like the double soul in MMBN6 better then the style change. Though different fighting styles with different elements are out, and only one fighting style. But each comes with their own element. So if you find yourself fighting against an enemy whose weakness you know, you can immediately change to suit the circumstances. So double soul is a good thing.

Just in case you don't know there is also the beast out ability and there called crosses and there is the beast cross.
