Good question, but I doubt you will get a 100% full proof answer. Just like all other technology, it is constantly advancing, and getting better. Prices are constantly coming down, speeds are increasing and quality is getting better. I would say, that if you don't absolutely need a Scanner, now, it is probably safe to say that the next generation will see vast improvements (especially with the Makerbot digitizer). However, we don't know if that next generation is 1 year off or 5 years off. I, myself am waiting because I think the current scanners are too slow for current technology.
