I doubt that there will be a revision for 3DS anytime soon as Nintendo had stated in their last statement that '3DS is a fully packed console from the beginning'. So there will not be 3DS-Lite until at least for another 1 or 2 years down the hill.

Another workaround is to setup MAC filtering even with encryption off. That would prevent malicious intruder.

I had never been an avid fan of Tales series. Not to agitate any Tales of fanboys here but I had tried Tales of Abyss and I'm not impressed. I'm more leaning towards turn based RPG games like FF series.

Now saving $$ to purchase RE: Revelations once it's in stock.
