If that 1500 crore base cap is true, I guess they will run into problems again. The two new teams Kochi and Pune suffered from the huge burden compared to SRH which only had to pay around 450 crores that to over 5 seasons. If BCCI haven't really plot out the monetary concerns like in 2011, they will face some sort of financial issues again. Let's see what they are gonna do.
Also I feel, 10 team tournament should be held if they had managed to clear out atleast 3 Months for IPL in FTP. If the same format of 2011 is to be followed it will more complicated than that of now for people to easily understand the tournament and what's going on. Until IPL had like 15+ teams where they can divide into two zones and do like NFL etc, it should be Double Robin+ Playoffs for the sake of simplicity imo.
