Please revive DVP for windows phone 8,.

I am begging you dell, to revive the only remaining phone with physical keyboard.  This whole onscreen keyboard trend on phones is ridiculous.  I cannot be productive on it when a whole keyboard fills up the whole screen.  I want a separate sliding physical keyboard.  I still use windows phone 7.8, but it is SLOWLY dying and I need it desperately for school and work.  They portrait keyboard is just wonderful.

Can't you guys just update the hardware and software?  I'm sure it won't cost you much, and I'm telling you there are still people out there like me who prefers physical portrait keyboard over onscreen keyboard.  The only remaining physical keyboard is blackberry Q10, but I'm already in windows phone ecosystem.  I am begging you Michael Dell!! Revive DVP!!! Thank you.
