Yes, it will be and it is. HSPA+ is deployed on places where spectrum refarming is not available. Also, it requires much less investment in RAN that supports HSPA comparing to LTE and it is faster to deploy. Also, you have much more HSPA+ devices in the market then LTE. In short term, HSPA+ will be installed to extend life of the existing networks before major spending on LTE.

Depending on the country, some mobile operators may not spectrum licenses for LTE. Therefore, their best approach is to provide cheap data plans in order to undercut the position of mobile operators with LTE networks, which have invested a lot of money in building the network.

For at typical user, it is better to have a HSPA+ with unlimited data plans than a LTE data plan that runs out after 5 minutes of maximum download rates. This was on the news a few weeks ago and I think it was basic LTE plan at vodafone UK, if I'm not mistaken.

Depends upon the country, In the present scenario I believe in India HSPA+ enhancements will win the race with LTE as well as HSPA+ will exist along with LTE.

In India the main reasons are lack of spectrum Standardization , non-availability of free spectrum in efficient frequency bands..

HSPA+ is the tip of the mountain with 3G technology, and LTE is simply the foundation for a new mountain. LTE, also known as 4G, is the most advanced telecommunications technology currently available, and is one that defines a clear path toward future developments, making it the most attractive choice for carriers these days.
