Jerry,
I'll answer your question as best as possible. As always, any target dates or version are "planned"...not set in stone. And please understand why: There are three variables I can adjust when developing software: resources, delivery date, and quality. My resources are fixed, and I won't budge on quality, so if a feature is harder to develop than we initially planned it's the date that moves.
Anyway, we originally planned to have portait mode in v7. And we planned to have v7 ready this month. But terrain & obstructions aren't done yet. So rather than delay v7 longer than necessary when this is through QA we'll release the terrain feature, then resume on portait mode and release 7.5 with that version. I suspect it will be done and released sometime this summer.
