Difficult to say mate but I can give you my opinion sure.
I personally think Cardsharing in the UK is on its knees and I doubt it will be back in the near future when it eventually dies out fully. You have to take into consideration that these companies have money to burn to ensure their encryption security is the best it can be which is in contrast to (albeit very clever) hackers who's budgets to hack the encryption will be much, much lower.
IPTV is a completely different ball game though, nothing needs to be hacked really. You're just broadcasting an image which doesn't really involve any hacking anything.
@TCIB is your guy when it comes to forecasting piracy landscape though :)
