While I do agree that the other two consoles project to have a better long-term value proposition, a) future libraries aren't the only facet that needs to be considered, and b) that certainly doesn't justify buying in at launch (much as it didn't for most people for the WiiU, though at launch it had better value prospects for me than the PS4 and XB1 did at their respective launches).
In some ways, the argument reminds me of the people on HFBoards wanting to pitched established talent for draft picks and unproven prospects... and then when they don't exceed expectations in two years, trade them for draft picks and prospects. In this case, I don't think it's a bad move, but the argument itself is just so cringe-worthy, especially when a take on same argument was used as a strike against one console ("has no games") and a pro for the other ("will have games")
