Agree. I don't think they will make a big deal with the 5 series and this motor - they'll just quietly drop it in for MY2012 or perhaps March 2012 production. Same for X3.
Also, the fact that the debut won't be in the X1 would seem to further bolster rumors that indeed the X1 will be delayed yet again for the US. Though I suppose it could still arrive late this year too.
