This wipe stuff get's really tiresome. What do you achieve with this? At best you pushed the problem back a few month. In worst cases you achieve nothing, because people simply don't drop the price and there will still be people able to afford said prices.
Someone who started early will always have an advantage over someone who started later. Again you achieve noting with a wipe, just postpone the problem.
Instead of something that only makes people unhappy how about thinking of something to actually solve the problem? Give a possibility to get soulcash via the ingame currency and make sure ingame items are plentifully on the markt. Problem solved.
I'll be blunt. This is simply a very, very bad idea. It look like more of an impulse rather then something a lot of tought went into. For example the OP states in no way how this would positively effect the game. It just takes it as given. It really shouldn't take much time to realize that this does not solve the problem and also would be a disaster for GFs credibility. So please stop that nonsense about a wipe. It's a bad idea and won't happen anyway.
