Just noticed some new combo kits.
These 2 aren't quite out yet. One is the entry level compact brushed drill and impact, two 1.5 batteries and a ds130 case. Another is a dcf887, dcd996, 2.0 battery, 5.0 battery, and ds130

I like the mixed battery kits. You get a compact for tight spaces and general use. You got your big for more runtime and power. The ds300 is a nice bonus.
Another combo kit I seen on acme. it includes a dcf887, dcd996, dcl040, dcs367, two 5.0 batteries, charger, and bag

I think DeWALT is finally starting fazing out the brushed 4+ tool combo kits with brushless tools. It's too bad the new kits come with a bag and not a ds300 or ds400.
