Always remember, when you use a comma... you put a space after it.
There isn't anything signifying that Christian is leaving ECW. And to be honest, I am kind of iffy on the entire subject.
I've really enjoyed, despite what many others may disagree on with Christian's stint here on ECW. He's treated as the main focal point of the show, doing great promos, matches, and carrying & elevating some of the talent. He's the main eventer of the show. Although it doesn't turn out like that on PPV.
If Christian went to RAW or SmackDown, although he's had a great wrestling career in both WWE & TNA, he'd probably be no higher then a upper-midcard on SmackDown probably near or at the same level as Rey Mysterio... or probably just a mid-card on RAW.
Christian is doing great work on ECW, and at the moment there is no need for him to be moved YET. However, back to the main question, and I do apologize for going so off topic... but I don't really think that there is a talent that could be the 'Bobby Lashley - Matt Hardy or Christian' of the show right now. I would say you could see Gregory Helms in that position, and I think he'd excel at it. However, adapting back 'The Hurricane' gimmick may push him down to not being able to be taken seriously enough as the top face of the show.
