I went to FamilyTree DNA (FTDNA) last night and verified the rumor – Rumor of FamilyTree DNA Big-Y 700 Upgrade from Big-Y 500. When I clicked on Add item, Big-Y 700 was only $179, and not $649. That’s a good price, but hopefully soon they will offer it cheaper for the DNA Day Sale next month. If you tested with Big-Y 700 or shortly before it was upgraded, you shouldn’t have to pay to upgrade. The Big Y Test Increases Again to Big Y-700 — DNAeXplained – Genetic Genealogy
I wasn’t sure if they were going to offer a decent price upgrade as the talk sounded like they were going to be doing a new sample. It looks like they are still running the test, but from the upgrade price, probably only running the new parts that are covered by Big-Y 700 that weren’t covered by Big-Y 500.
