Well the upgrade to the ALink bus didn't happen thanks to the northbridge but thanks to the SB. The 790 NB already supported PCIE 2.0 but it's accompanying SB didn't. Since ALink is nothing more than a PCIE connection, you see where i'm getting at. So 790 & 890 where the same silicon and AMD has only upgraded the southbridge since then.
I think the reason why AMD is so reluctant to upgrade the NB is bc the next step for them would be to integrate a fully new NB into the CPU. So I guess all the (limited) resources are going into that.
