I am not a follower of the WWE, but this topic came up the other day on the radio, and got me thinking... with all the drama in the WWE, there are a few really good reasons why this might be happening. My thoughts are that the "death" is simply a good way for him to escape for a little while. Possible reasons are as follows.
1) Vince is sick, needing some time off to recover. Maybe he needed some heart surgery, had appendicitis, possibly even rehab. I don't know much about the guy, so the theorites are purely speculative.
2) Vince needs a vacation. There is probably no good way to write into the WWE storyline a 6 month sailing trip around the world, or a 2 month vacation in Europe. Maybe he just wanted a bit of a break?
3) Retirement. Perhaps the guy is just tired of wrestling, and wants to just turn his position into an office job? What better way than to write his own death? Lots of media hype, concerned people desperately tuning in to find out what happens...
4) Storyline alone. Perhaps they just wanted some hype into some upcoming plot? Tag-teaming with the Undertaker or something? LOL An introduction of some new "death theme" guy?
Either way, this is a break chance for him to take a break and make lots of money in the process! In hindsight though, considering the situation with Benoit, the timing seems a bit odd...
Should be interesting to see how Vince decides to come back, and how it gets written in (assuming of course he comes back)
