will my ideal tablet be a reality?

[knrstz64]

I have a nexus 7. I am fairly happy with it and haven't experienced much lag. However I don't know if it will make it another year based on longevity reports. I want a high end 7 or 8 inch tablet. Pretty much I won't the xperia tablet z in a smaller form. I can live with nicer plastic but i don't want the plastic of the note 8. Metal would be nice. I want at least 32gb plus a misco SD slot. Of course a great display is important. I would pay $350-$400 if someone would make this. Any rumors out there?
