I did a quick Google search and found something over at XDA where someone shares the same opinion as you regarding 4430/4460 being from same wafer though.

No, he doesn't share my opinion at all. Thanks for the link, I'll have to have a chat with him about this.
I believe the design documentation fully supports that the 4430 and 4460 are actually totally separate variants of the OMAP4 - and are NOT a speed/quality numbering scheme.
A post on XDA doesn't make it so.
