BMugFord makes a great point about Dot Asia being pointless because local CCTLD are well established. That's the exact reason why I bought into Dot Asia. If the local are well known, established, popular, and is growing exponentially, then Dot Asia will also benefit from that growth.
I told myself, I would not invest in Dot Asia if I see that .cn, .jp, .kr, .in is small not growing, not popular, but its the exact opposite, which is the reason to invest.
.Asia
.TV
.Tel
.BiZ
I say Dot Asia has the greatest potential as noted (my opinion) from BMugFord statement that the region local cctlds' are growing, large, and popular.
