...or at least let us know when Garbage Day is, Dave!
  
 True, it IS a lot for a kit --- I paid a pretty penny for the Nimix 35th scale resin Vietnam-era Monitor (over $300.00) but it was something I wanted really badly --- so bad that I saved up for it and did a little freelance work on the side to get it. Took about four months, but I was able to purchase it. 
If people want a kit badly enough, they will save up or find a way... That being said, $600.00 IS a BIG financial hit, so I would agree with Shermie that sales of a kit this costly will be limited. This is obvious given the high sticker price. 
And yeah, it is always a gamble that a company will release a much cheaper version of the expensive resin kit --- but that is the nature of our hobby...unless it is a piece of WWII German armor, there is no certainty that a kit will be mass produced.  Who knows, given Italeri and Trumpeter's welcomed boldness in thinking outside the kit box by releasing 35th scale landing craft (including Ital's August LCVP release, woo-hoo!) , perhaps kits such as this gunboat could follow. I kinda wish Tamiya had continued along this route after they kitted the PBR...oh, well. 
And even though this is a fantastic-looking kit (love the T-34 turret!), I would rather save up the big bucks for some of those Masterpiece Models 35th scale Vietnam-era Riverine craft (via the Squadron shop), if they ever come out!  Anybody hear anything about these lately...?
To each his own (wallet)!!
