According to the GitHub site, we're now 3 days away from 30 June "Beta Milestone: All comments / issues from Alpha have been addressed, Testing complete". We're also less than 25 days from when SEGWIT2X is supposed to be ready for signalling by miners.

I'm not a software expert but I have read several places that this schedule is rather aggressive. Has anyone with coding or software project management experience reviewed the GitHub site recently and if so can you provide your opinion on it's status? Is it behind, ahead, or on schedule? Would be good if you could post links to evidence or comparison with other relevant software projects to back up opinion.

I'm not looking for opinion about the politics of it (whether 2x is a good or bad idea), I just want to understand from a technical/software development perspective based on reviewing the evidence available today, the chances of SEGWIT2X being ready on 21 July.
