guys grow up. X3 might run on X2 chips but most of the on-the-fly features will be disabled unless it's on the X3 chip. Unless the X3 is an OS (like how xenium, smartxx, x-chip is done) then i doubt it would run on other chips.
I haven't read mutch about the X3 but I think it goes somthing like that (be better to wait till it's released rather than bashin each & every team).
However if you have an X2 or 3rd generation/flashable chip I think I read somewere on the Xecuter news that they are going to release an updated X2 bios (correct me if i'm wrong). So the saying goes, if it aint broke don't fix it.
Also about the solderless adapter thing, Xecuter did say thank you to Ozxodus for there design, they didn't steel it, they improved it.
