Up! Concept and other camper ideas

[Pushing Fifty]

I tried to ask this question on the Tex, and nobody responded, so I'll try here. A roomier version of the Up! called the Space Up! was said to be on VW's drawing board. For a while VW.com listed it in the upcoming and concept cars section, but now all I see is the smaller 3-door version. Does anyone know whether or not the Space Up! version has been killed before it even begins? I had high hopes for this vehicle coming to the US somewhere around 2014 and envisioned a small 1-person camper conversion.

I've looked into doing this with either a Passat or Jetta Wagon as well, but they are too short, and I'm only 5'8" as it is! Just out of curiosity, does anyone know whether a Tiguan with the rear seats folded flat has at least 6 feet of lying room?
