About time! Anyone whining about this need to get their marbles examined.
The blockchain size is already turning into a serious problem... Don't speak with such a vicious tone when you don't know what you are talking about.
BlockChain is already almost 40 GB of size, but this change is inevitable. There is no problem with our current terabyte hard disks to storage it. And you dont have to run full node wallet like Bitcoin Core at all.
Electrum or MultiBit will do just fine.
That and by the time blocks are actually 20mb each the price of storage will continue to be lower, just like the price per gigabyte was 1.24 in 2005 and in 2014 it was $.03 every 5 years it is ATLEAST been a third of the price and some years a large jump. 1995 $/gb was $1,120. In 2000 it was $11/gb in 2005 the $1.24 and in 2010 it was .09$/gb . Storage price shouldn't be an issue it is getting cheaper compared to the requirements needed.
