I'll miss it, if for no other reason than I had some NFL-esque stuff to watch during the NFL-downtime!!! :lollol:
As for a "developmental league".. there are already quite a few minor leagues around (ie. Chris's King County Jags, and no I'm not forgetting you Lisa

), so there is already a structure there. They could have something to build on there............? I dunno.
Arena League? It's a different game. Yes, they have some similar rules, but it's a different game.
Personally, I don't think that a league on the level of NFLE would have any more sucess here in the US than it did in Europe. I kinda hoped that the interest of the NFL game in England, and the increased attendance this past few years would have kept NFLE going, but oh well.
*sigh*
