the biggest long term problem i see (and the article partially addresses) is all these pros bumhunting the low-stakes games because there's no reason not to. it doesn't take any additional time nor mental focus to join some microstakes games like it would if you were playing online poker.
anyone who play dfs, how are money withdrawals from the site? is it relatively quick/easy to get money out of your accounts? otherwise i definitely see that as a huge risk just like it was towards the end of the online poker boom.
