They definitely need a faster unloading rate and bigger grain tank. They already tried the 7010 around here and the custom cutter was not impressed. The 1.9 unloading rate is kinda lame by today's standards.
in 2007 7010 will be released (not a 2388, but it will be a smaller horsepower version of 8010-around 330hp) 2388 will be called 6010, 2377 will be a 5010. 5010 and 6010 will look more like 8010 and also have bigger unloaders.
