Hi Vitoner,
The graph below shows the Slacker Backer state as of today, 15th of April 2016.

I made a quick calculation:
With 10 new backers per day pledgind 60$ each, it will take 666.66 days to reach $7,000,000...
In other words, we will NEVER reach the next stretch goal unless something BIG happens before the release of Shenmue 3 :-o
