Atiuta pretty well hit the nail on the head.
I am a LTC for one of the web's favorites LOCO companies and all I want to know is before I jump into the desert is if I could expect to get an upgrade in about 18 months to 2 years.
The answer is simple. You cannot "expect" an upgrade in 18 months to 2 years. That's not to say it isn't possible, but to "expect" it would be reckless.
