I guess they are just based off rumours though
Read this if you're interested
I have tried both sense and aosp ics, but I still keep coming back to sense 3.5 gingerbread, either affinity or trinity sensation xl.
Because there are some glitches, bugs and things not working, I will stay on gingerbread. And I like sense
But the features and improvements in the ics roms look very promising, I liked sense 4 very much
Just make a nandroid backup and flash it, then go back to your backup when you are bored lol
I like to go back to a stable rom where everything works
