This guy doesn't know ****. He's just wildly guessing and is happy for the twitter likes and replies(and maybe some new followers), that's why he keeps posting about Apple Pay. Can do the same: post 10 dates and if the date comes and AP hasn't launched just tweet "oh there have been some internal delays", "some banks are not ready yet", "new banks coming along that need the infrastructure slightly updated", etc... Only Apple knows when, and maybe some C-Levels at the banks, that have signed some bulky NDAs and they'll never risk getting sued by telling someone.
Sorry, but no. His job is literally to work with insiders of different banks. He also correctly predicted the launch of Google Pay and also that comdirect will be a launch partner
