Really?? The ICS source has been out for all of what, 2 weeks, and your expecting new phones to already have it? Im sure both the D4 and the RAZR will have ICS in Q1 2012.
I agree, D4 won't have ICS on release. But either by OTA or rom it should have it by Spring. The D3 took just 6 weeks to a reliable 1-click root. And the main focus of rom development now, I would think, will be porting ICS to as many phones as possible. I'd love to have it on my DX... [and/or on the used T-bolt I'm looking for (PM)] ...in case I hold out for summer and the D5.
We do have choices.
Perspective instantiates reality.
