DSL-N66U vs DSL-N55U

[bmn1]

On the regional website DSL-N66U is not posted yet but on the global site it is.

Apart from the VDSL and N900 upgrade what is the advantage of DSL-N66U over DSL-N55U?

how is not having the 3 large antennas a good thing?
Why does the new one has less RAM?


should I get DSL-N66U instead of DSL-N55U now?
