Mach 1.8 was the goal, but they didn't seemed to reach it yet, some reports suggested the small but rather thick wings as a possible problem. Most of the drag reduction features that the MK2 will have, are already implemented in the latest LSP version, like the new APU coverings, or some changes at air intakes. Drag is sadly a general problem for our designs as it seems, since most of our aircrafts are facing the same problems (see the latest changes of LCH for example). So finding thigs to counter that, next to weight reductions and increased thrust will be important to reach the initial goals.
LCA MK2 will have several capabilities that are similar to Gripen NG, be it the same engine, AESA radar, but the Gripen NG is meant to be a medium class 4.5 gen fighter and therfor includes changes to carry higher loads too. LCA MK2 will be a 4.5 gen fighter too, but still aimed on the light class. Without additional hardpoints, or more internal fuel carriage, it won't be able to have similar loads like the Gripen. But then again, it don't have to, since IAF has way better platforms for these roles. As an interceptor with CAS capabilities, it will be very comparable to the Gripen again, but we will have to wait for all details of the MK2 till we can say more.
