I think it's fair to say the X10, released nearly 6 years ago, has had its time. I still have mine as a backup and have reverted to stock ROM and kernel.
Don't get me wrong, I'd love to see a more modern kernel and ROM on the X10 for sh*ts and giggles. But I don't think it's going to happen now as it's all gone very quiet on here.
It was a shame that the SEMC Debrand 4.1.2 ROM didn't get more development as that looked very promising.
