Nikon still have the D300s (their semi-pro dx) update to deliver - the D400 to give it a likely name. This update is well overdue. They have consistently pushed their FF tech (D4, D800) down to the high end dx (D400) series. Their dilemma is to still maintain differentiation between the D400 and the D7100. In reality the D7000 replaced the D90 as the high end consumer model, with the new D400 still being the semi-pro high end dx model.
The Nikon line up is entry dslr D3200 dx, mid consumer dslr D5100 dx, high end consumer dslr D7000 dx, semi-pro dslr D400 dx, small pro dslr D800 ff, pro dslr D4. Thom Hogan has done some analysis that suggests they will end up with a 7 body line up eventually - all hitting different segments and at different price points. They need to keep some feature space between each model and that affects what they can put in both the D400 and the D7100.
They still have the issue that the dslr marketplace is maturing and upgraders don't give them the volume they need to grow and survive.
So where verse Pentax K-5 upgrade - the current K-5 sits between the D7000 and the D300s in terms of IQ, features, build, etc. It seems to have done well enough in it's niche. I would expect that the K-5 upgrade will try and occupy the same niche - semi-pro APS-C offering the uniqueness of a small WR body.
Whether Pentax can keep up in the feature arms race remains to be seen - they achieved it ok with the current K-5.
They know very clearly what the competition is likely to look like, so they will have their targets.
Don't forget the Canon 7D refresh will also come this year - the current 7D is a K-5 competitor and a very capable camera.
