For people who are budget minded, keeping a 10 speed bike will make sense for the next few years. I have a stack of 10 speed Dura Ace cassettes I use on my 5700 bike I got for $25 apiece.
Not everyone has multiple wheelsets. Purchasing 5800 may not be an upgrade for them, it could be part of their complete bike purchase.
No one is forcing you to go 11spd, but in the not to distant future all quality road/CX bikes will be 11spd.
Today or tomorrow I'll be ordering a 6800 groupset, and the parts to rebuild my rear wheels. I could save money, and get 6700, but a groupset lasts me about 90k miles(6-7 years). Quality 10spd parts will be hard to find long before then.
